sat考试物理方面必备词汇

sat考试物理方面必备词汇物理是sat考试的一个难点，考生有必要在物理方面多准备一些重要的高频词汇。

为大家精心准备了sat考试物理方面必备的一些词汇，欢送大家前来阅读。

ImpulseA vector quantity defined as the product of the force acting on a body multiplied by the time interval over which the force is exerted.Incident rayWhen dealing with reflection or refraction, theincident ray is the ray of light before it strikes the reflecting or refracting surface.Inclined planeA wedge or a slide. The dynamics of objects sliding down inclined planes is a popular topic on SAT II Physics.Index of refractionThe index of refraction n = c/v of a substance characterizes the speed of light in that substance, v. It also characterizes, by way of Snell's Law, the angle at which light refracts in that substance.Induced currentThe current induced in a circuit by a change in magic flux.Inelastic collisionA collision in which momentum is conserved but kiic energy is not.InertiaThe tendency of an object to remain at a constant velocity, or its resistance to being aelerated. Newton’s First Law is alternatively called the Law of Inertia because it describes this tendency.Inertial reference frameA reference frame in which Newton’s First Law is true. Two inertial reference frames move at a constant velocity relative to one another. Aording to the first postulate of Einstein’s theory of special relativity, the laws of physics are the same in all inertial reference frames.Instantaneous velocityThe velocity at any given instant in time. To be contrasted with average velocity, which is a measure of the change in displacement over a given time interval.Internal energyThe energy stored in a thermodynamic system.Inversely proportionalTwo quantities are inversely proportional if an increase in one results in a proportional decrease in the other, and a decrease in one results in a proportional increase in the other. In a formula defining a certainquantity, those quantities to which it's inversely proportional will appear in the denominator.Isolated systemA system that no external force acts upon. Objects within the system may exert forces upon one another, but they cannot receive any impulse from outside forces. Momentum is conserved in isolated systems.IsotopeAtoms of the same element may have different numbers of neutrons and therefore different masses. Atoms of the same element but with different numbers of neutrons are called isotopes of the same element.KelvinA scale for measuring temperature, defined such that 0K is the lowest theoretical temperature a material can have. 273K = 0oC.Kepler’s First LawThe path of each pla around the sun is an ellipse with the sun at one focus.Kepler’s Second LawIf a line is drawn from the sun to the pla, then the area swept out by this line in a given time interval is constant.Kepler’s Third LawGiven the period, T, and semimajor axis, a, of a pla’s orbit, the ratio is the same for every pla.Kinematic equationsThe five equations used to solve problems in kinematics in one dimension with uniform aeleration.KinematicsKinematics is the study and description of the motion of objects.Kiic energyEnergy associated with the state of motion. The translational kiic energy of an object is given by the equation .Kiic frictionThe force between two surfaces moving relative to one another. The frictional force is parallel to the plane of contact between the two objects and in the opposite direction of the sliding object’s motion.Kiic theory of gasesA rough approximation of how gases work, that is quite aurate in everyday conditions. Aording to the kiic theory, gases are made up of tiny, round molecules that move about in aordance with Newton’s Laws, and collide with one another and other objects elastically. We can derive the ideal gas law from the kiic theory.Magic fluxThe dot product of the area and the magic field passing through it. Graphically, it is a measure of the number and length of magic field lines passing through that area. It is measured in Webers (Wb).MagnificationThe ratio of the size of the image produced by a mirror or lens to the size of the original object. This number is negative if the image is upside-down.MagnitudeA property mon to both vectors and scalars. In the graphical representation of a vector, the vector’s magnitude is equal to the length of the arrow.Margin of errorThe amount of error that’s possible in a given measurement.MassA measurement of a body’s inertia, or resistanc e to being aelerated.Mass defectThe mass difference between a nucleus and the sum of the masses of the constituent protons and neutrons.Mass numberThe mass number, A, is the sum of the number of protons and neutrons in a nucleus. It is very close to the weight of that nucleus in atomic mass units.MaximaIn an interference or diffraction pattern, the places where there is the most light.Mechanical energyThe sum of a system’s potential and kiic energy. In many systems, including projectiles, pulleys, pendulums, and motion on frictionless surfaces, mechanical energy is conserved. One important type of problem in which mechanical energy is not conserved is the class of problems involving friction.MediumThe substance that is displaced as a wave propagates through it. Air is the medium for sound waves, the string is the medium of transverse waves on a string, and water is the medium for ocean waves. Note that even if the waves in a given medium travel great distances, the medium itself remains more or less in the same place.Melting pointThe temperature at which a material will change phase from solid to liquid or liquid to solid.MesonA class of elementary particle whose mass is between that of a proton and that of an electron. A mon kind of meson is the pion.Michelson-Morley experimentAn experiment in 1879 that showed that the speed of light is constant to all observers. Einstein used the results of this experiment as support for his theory of special relativity.MinimaIn an interference or diffraction pattern, the places where there is the least light.MoleThe number of hydrogen atoms in one gram of hydrogen, equal to . When counting the number of molecules in a gas, it is often convenient to count them in moles.。

常用SAT2物理测试术语（1）SAT2物理考试中有很多专业术语词汇，三立在线教育为你带来常用SAT2物理测试术语（1），希望对你有所帮助，更多资讯请访问三立在线，专业老师为你在线解答相关疑问。

AAbsolute zeroThe lowest theoretical temperature a material can have, where the molecules that make up the material have no kinetic energy. Absolute zero is reached at 0 K or –273o C.AccelerationA vector quantity defined as the rate of change of the velocity vector with time.ActivityIn radioactive substances, the number of nuclei that decay per second. Activity, A, will be larger in large samples of radioactive material, since there will be more nuclei.Alpha decayA form of radioactive decay where a heavy element emits an alpha particle and some energy, thus transforming into a lighter, more stable, element.Alpha particleA particle, which consists of two protons and two neutrons. It is identical to the nucleus of a helium atom and is ejected by heavy particles undergoing alpha decay.AmplitudeIn reference to oscillation, amplitude is the maximum displacement of the oscillator from its equilibrium position. Amplitude tells how far an oscillator is swinging back and forth. In periodic motion, amplitude is the maximum displacement in each cycle of a system in periodic motion. The precise definition of amplitude depends on the particular situation: in the case of a stretched string it would be measured in meters, whereas for sound waves it would be measured in units of pressure.Angle of incidenceWhen a light ray strikes a surface, the angle of incidence is the angle between the incident ray and the normal.Angle of reflectionThe angle between a reflected ray and the normal.Angle of refractionThe angle between a refracted ray and the line normal to the surface.Angular accelerationA vector quantity, , equal to the rate of change of the angular velocity vector with time. It is typically given in units of rad/s2.Angular displacementThe net change, , in a point’s angular position, . It is a scalar quantity.Angular frequencyA frequency, f, defined as the number of revolutions a rigid body makes in a given time interval. It is a scalar quantity commonly denoted in units of Hertz (Hz) or s–1.Angular momentumA vector quantity, L, that is the rotational analogue of linear momentum. For a single particle, the angular momentum is the cross product of the particle’s displacement from the axis of rotation and theparticle’s linear momentum, . For a rigid body, the angular momentum is a product of the object’s moment of inertia, I, and its angular velocity, .Angular periodThe time, T, required for a rigid body to complete one revolution.Angular positionThe position of an object according to a co-ordinate system measured in s of the angle of the object from a certain origin axis. Conventionally, this origin axis is the positive x-axis.Angular velocityA vector quantity, , that reflects the change of angular displacement with time, and is typically given in units of rad/s. To find the direction of the angular velocity vector, take your right hand and curl your fingers along the particle or body’s direction of rotation. Your thumb then points in the direction of the body’s angular velocity.AntinodeThe points midway between nodes on a standing wave, where the oscillations are largest.AtomThe building blocks of all matter, atoms are made up of a nucleus consisting of protons and neutrons, and a number of electrons that orbit the nucleus. An electrically neutral atom has as many protons as it has electrons.Atomic numberA number, Z, associated with the number of protons in the nucleus of an atom. Every element can be defined in s of its atomic number, since every atom of a given element has the same number of protons.Axis of rotationThe line that every particle in the rotating rigid body circles about. 单词的记忆要靠长期的坚持，考生们一定要持之以恒，每天都拿出来看一看背一背，让这些词汇在大脑中形成长期记忆，这样就不会轻易地忘记背过的词汇了。

That's the sound kids upand down the country do not want tohear – the alarm bell.The school year has just started andchildren across the UK have to wakeup bright and early to go to school.But students at one school in north-east England can lie in for an extrahour before they go to school.Kids can now have a lie in on school days.Monkseaton High School has been allowing its pupils to come into school an hour later than other schools.The headmaster, Dr Paul Kelley, says that this approach helps students pay more attention in class.He feels that young people are more productive later on in the day and that a late start may be better for their school career than an early one.Dr Kelley told the BBC that "teenagers don't function very well in the morning and their need to sleep is biological".It seems that this novel approach to teaching shows positive results. The school has already seen a drop in the number of pupils playing truant by 27%.More importantly, Dr Kelley also said that exam results have improved by 20-30% over the past year.Lessons at Monkseaton High School begin at 10am and finish at 3.40pm; however, the school opens from 8am to 5pm.bright and early 明亮的大清早儿lie in 躺在床上Sealed with a Kiss 吻之展英语学习点: Kissing V ocabulary 有关‘吻’的词汇"Get your gob in gear for a night!" Thatwas the invitation to a recent event inLondon celebrating the art of kissing.People were asked to put on lip gloss,press their mouths against a piece ofcard and then write a messagedescribing a memorable smacker.One woman mentioned her experienceof giving a peck on a baby's cheek.William and Catherine: Was this the kiss of 2011?Another moaned about a sloppy kiss she had received from a new boyfriend.Anthropologists suggest the origins of the snog aren't romantic: in primitivetimes mothers chewed food and gave it to their babies mouth-to-mouth.Today, kissing etiquette varies according to local customs. In some countries people will greet you with one peck, in others with two or more.In France, they are so keen on kissing that they have even got a smackernamed after them: the French kiss. That's the one where tongues get busy.But in India a smooch in public could land you in jail. In Germany, you won'tbe giving your freedom the kiss-off but an inappropriate snog could be thekiss of death for your promotion. The Knigge Society says the practice of greeting work colleagues with a kiss is uncomfortable for many Germans.The longest continuous snog ever recorded lasted for more than 46 hours. AThai couple locked lips in a special event in the beach resort of Pattaya.But what about Britain? Well, we Brits are much less shy than we used to be about kissing in public, but not everyone is keen. In particular, air kissing isseen as an affectation of the rich and beautiful classes.

A physicist from the University ofSurrey, Jim Al-Khalili, believes that the current consensus is correct andthat the light-speed barrier is impossible to surpass.He has tried to pick holes in the methodology of the Cern researchers. Sosure is Al-Khalili that they have made an error in their measurements that he has decided to defend the laws of physics by challenging the laws of social convention.Al-Khalili said: "If the Cern experim ent proves to be correct… I will eat my boxer shorts on live TV."to turn something on its head 完全改变subatomic particle 次原子粒子to overturn 推翻long accepted 长期被认可的cornerstone 基石theory of special relativity 狭义相对论the concept of causality 因果关系的概念implications 影响，含义，推断mainstream theory 主流理论time travel 时空穿梭hypothesis 假设science fiction 科幻小说experiment 实验sceptic 怀疑论者current consensus 当前的共识the light-speed barrier 光速障碍overcome 克服to pick holes in something 寻找漏洞methodology 方法论，方法学social convention 社会惯例，常规The Silver Smokescreen! 银幕与烟幕英语学习点: Film V ocabulary 电影词语Here's looking at you kid!Lights, camera, action! When we go to the cinema we sometimes experience scenes that reflect reality. But does the imagery affect our behaviour?A new study has found that teenagers who see actors smoking on screen are more likely to take it up.5,000 15 year olds in the UK were questioned and many said seeing blockbuster films that depict smoking would encourage them to light up.This research by Bristol University looked at the potential influence of some of the 360 top US box office films released between 2001 and 2005 that showed smoking, such as Spider-Man and The Matrix.Now some experts are calling for a change in film certification so the under-18s are unable to see actors smoking on the silver screen.Dr Andrea Waylen, who led the research, said "We saw a linear relationship between adolescent smoking and the number of films they had seen depicting smoking."In the UK, films with ratings U (universal) or PG (parental guidance) ban scenes showing drug misuse but not cigarette smoking.But is seeing the lead puffing on a cigarette really glamorising smoking? If so, would the motion-picture industry have to re-think what goes in every scene from the start to the end credits?Simon Clark, director of the smoker's group Forest, said: "We go to the cinema to escape from the nanny state… what next? Should government reclassify films that feature fat people as well in case they are bad role models?"lights, camera, action!灯光，开拍，动作！imagery 想象中的blockbuster 畅销大片depict 表现，刻画box office 票房film certification （针对观众年龄的）电影限制规定the silver screen 银幕ratings 评级PG (parental guidance) 家长指导级the lead 领衔主演glamorising 潇洒的motion-picture 电影scene 场面the end credits 影片末尾的演员表reclassify 重新划定role models 榜样Take Away English 随身英语Reap What you Sow! 园艺在英国盛行英语学习点: Gardening V ocabulary 和园艺有关的词汇Odd things are happening to Brits... weseem to be developing green fingers!The number of people growing their ownfruit and veg has almost doubled in thepast year, according to Gardeners' Worldmagazine.Gardens and allotments across the UKhave been put to use as people discoverthe joys of home-grown produce.Brits are developing green fingers!But not everyone has space for a vegetable patch or a flowerbed. And sometimes a window box just isn't enough of a gardening challenge.That's why some people have been turning to guerrilla gardening. This is when people plant flowers or vegetables in public spaces to make them greener and more pleasing to the eye.Many people would approve of prettifying towns and cities, but guerrilla gardening is not strictly legal. Therefore, this type of gardening often takes place in the dead of night.But the stereotype of the keen gardener is not someone who wears combat boots and breaks the law. It is of someone who wears wellies and spends all their time in greenhouses and potting sheds. We expect such a person toknow every aspect of how to tend and cultivate their plants.Yet, despite the increase in people growing their own, more than half of the UK population still do not know when 18 out of the top 22 fruit and vegetables are in season, according to Gardeners' World.It seems that Britain still has some way to go before we can justifiably be called a nation of gardeners.to reap what one sows 种瓜得瓜，种豆得豆to have green fingers 形容有园艺才华的人fruit and veg 蔬果allotment [英](划成小块出租的)菜地home-grown 自家种植produce 农作物vegetable patch 菜地flowerbed 花坛window box 放在窗台上的长花盆guerrilla 游击队式的to prettify something 美化某物the dead of night 深夜wellies 雨靴greenhouse 温室potting shed 盆栽棚to tend something 照顾某物to cultivate something 培养某物to grow one's own 种植自己的蔬菜和水果in season 当季的a nation of gardeners 园艺大国Web Words Hit Dictionaries 网络词录入字典英语学习点: New Words in the Dictionary 字典新词The web-savvy amongst you willknow that just as a mouse is nolonger only a rodent, a tweet isn'tnecessarily a noise made by a bird.Nearly a quarter of the new wordsadded to the latest edition of theChambers Dictionary come frominternet culture, with the economicrecession and climate change alsocontributing strongly.Hmm, I wonder if I can find quantitative easing…The internet age's ability to reinvent old words with new meanings continues.

A study suggests that it is very efficient at processing good news: about 80% of people have a tendency to see the glass as half-full, not half-empty, even if they don't consider themselves to be optimists.The good news is that this brings a health benefit. Being upbeat and having a positive outlook on life reduces anxiety. A study of nearly 100,000 women showed a lower risk of death from heart disease amongst optimists.But there are pitfalls to always having an upbeat attitude. The authors of the study point out that the 2008 financial crisis may have been caused by analysts overestimating their assets' performance even in the face of clear evidence to the contrary.There are personal health risks too. Dr Tali Sharot, lead researcher, said: "'Smoking Kills' messages don't work as people think their chances of cancer are low. There's a very fundamental bias in the brain."But, as they say, every cloud has a silver lining. Even if seeing the world through rose-tinted glasses poses a risk to our health, it's not somethingthat is likely to cause us to lose sleep.Let's just keep our chins up and keep smiling!optimism 乐观主义sanguine （正式用语）满怀希望的to see the glass as half-full, not half-empty 表示同样半杯水，乐观的人觉得杯子是半满，悲观的人觉得杯子是半空的。

CalorieThe amount of heat needed to raise the temperature of one gram of water by one degree Celsius. 1 cal = 4.19 J.CelsiusA scale for measuring temperature, defined such that water freezes at 0ºC and boils at 100ºC. 0ºC = 273 K.Center of curvatureWith spherical mirrors, the center of the sphere of which the mirror is a part. All of the normals pass through it.Center of massGiven the trajectory of an object or system, the center of mass is the point that has the same acceleration as the object or system as a whole would have if its mass were concentrated at that point. In terms of force, the center of mass is the point at which a given net force acting on a system will produce the same acceleration as if the system’s mass were concentrated at that point.Centripetal accelerationThe acceleration of a body experiencing uniform circular motion. This acceleration is always directed toward the center of the circle.Centripetal forceThe force necessary to maintain a body in uniform circular motion. This force is always directed radially toward the center of the circle.Chain reactionThe particles and energy released by the fission or fusion of one atom may trigger the fission or fusion of further atoms. In a chain reaction, fission or fusion is rapidly transferred to a large number of atoms, releasing tremendous amounts of energy.Charles’s LawFor a gas held at constant pressure, temperature and volume are directly proportional.Coefficient of kinetic frictionThe coefficient of kinetic friction, , for two materials is the constant of proportionality between the normal force and the force of kinetic friction. It is always a number between zero and one.Coefficient of linear expansionA coefficient that tells how much a material will expand or contract lengthwise when it is heated or cooled.Coefficient of static frictionThe coefficient of static friction, for two materials is the constant of proportionality between the normal force and the maximum force of static friction. It is always a number between zero and one.Coefficient of volume expansionA coefficient that tells how much the volume of a solid will change when it is heated or cooled.Coherent lightLight such that all of the associated waves have the same wavelength and are in phase.CollisionWhen objects collide, each object feels a force for a short amount of time. This force imparts an impulse, or changes the momentum of each of the colliding objects. The momentum of a system is conserved in all kinds of collisions. Kinetic energy is conserved in elastic collisions, but not in inelastic collisions. In a perfectly inelastic collision, the colliding objects stick together after they collide.Completely inelastic collisionA collision in which the colliding particles stick together.ComponentAny vector can be expressed as the sum of two mutually perpendicular component vectors. Usually, but not always, these components are multiples of the basis vectors, and ; that is, vectors along the x-axis and y-axis. We define these two vectors as the x- and y-components of the vector.CompressionAn area of high air pressure that acts as the wave crest for sound waves. The spacing between successive compressions is the wavelength of sound, and the number of successive areas ofcompression that arrive at the ear per second is the frequency, or pitch, of the sound.Concave lensAlso called a diverging lens, a lens that is thinner in the middle than at the edges. Concave lenses refract light away from a focal point.Concave mirrorA mirror that is curved such that its center is farther from the viewer than the edges, such as the front of a spoon. Concave mirrors reflect light through a focal point.ConductionHeat transfer by molecular collisions.Conservation of Angular MomentumIf the net torque acting on a rigid body is zero, then the angular momentum of the body is constant or conserved.Conservation of momentumThe principle stating that for any isolated system, linear momentum is constant with time.Constant of proportionalityA constant in the numerator of a formula.Constructive interferenceThe amplification of one wave by another, identical wave of the same sign. Two constructively interfering waves are said to be “in phase.”ConvectionHeat transfer via the mass movement of molecules.Convex lensAlso called a converging lens, a lens that is thicker in the middle than at the edges. Convex lenses refract light through a focal point.Convex mirrorA mirror that is curved such that its center is closer to the viewer than the edges, such as a doorknob. Convex mirrors reflect light away from a focal point.CosineThe cosine of an angle in a right triangle is equal to the length of the side adjacent to the angle divided by the length of the hypotenuse.CrestThe points of maximum displacement along a wave. In traveling waves, the crests move in the direction of propagation of the wave. The crests of standing waves, also called anti-nodes, remain in one place.Critical angleFor two given media, the smallest angle of incidence at which total internal reflection occurs.Cross productA form of vector multiplication, where two vectors are multiplied to produce a third vector. The cross product of two vectors, A and B, separated by an angle, , is , where is a unit vector perpendicular to both A and B. To deine which direction points, you must use the right-hand rule.CycleIn oscillation, a cycle occurs when an object undergoing oscillatory motion completes a “round-trip.” For instance, a pendulum bob released at angle has completed one cycle when it swings to and then back to again. In period motion, a cycle is the sequence through which a system once during each oscil-lation. A cycle can consist of one trip up and down for a piece of stretched string, or of a compression followed by a rarefaction of air pressure for sound waves.以上就是为考生们介绍的SAT2物理词汇的汇总，供考生们参考。

SAT II物理考试常用术语词汇Physics Glossary
The following list defines all of the bold-faced words you encountered as you read this book.
A–D
A
Absolute zero
The lowest theoretical temperature a material can have, where the molecules that make up the material have no kinetic energy. Absolute zero is reached at 0 K or –273º C.
Acceleration
A vector quantity defined as the rate of change of the velocity vector with time.
Activity
In radioactive substances, the number of nuclei that decay per second. Activity, A, will be larger in large samples of radioactive material, since there will be more nuclei.
Alpha decay
A form of radioactive decay where a heavy element emits an alpha particle and some energy, thus transforming into a lighter, more stable, element.
Alpha particle
A particle, , which consists of two protons and two neutrons. It is identical to the nucleus of a helium atom and is ejected by heavy particles undergoing alpha decay.
Amplitude
In reference to oscillation, amplitude is the maximum displacement of the oscillator from its equilibrium position. Amplitude tells how far an oscillator is swinging back and forth. In periodic motion, amplitude is the maximum displacement in each cycle of a system in periodic motion. The precise definition of amplitude depends on the particular situation: in the case of a stretched string it would be measured in meters, whereas for sound waves it would be measured in units of pressure.
Angle of incidence
When a light ray strikes a surface, the angle of incidence is the angle between the incident ray and the normal.
Angle of reflection
The angle between a reflected ray and the normal.
Angle of refraction
The angle between a refracted ray and the line normal to the surface.
Angular acceleration
A vector quantity, , equal to the rate of change of the angular velocity vector with time. It is typically given in units of rad/s2.
Angular displacement
The net change, , in a point’s angular position, . It is a scalar quantity.
Angular frequency
A frequency, f, defined as the number of revolutions a rigid body makes in a given time interval. It is a scalar quantity commonly denoted in units of Hertz (Hz) or s–1.
Angular momentum
A vector quantity, L, that is the rotational analogue of linear momentum. For a single particle, the angular momentum is the cross product of the particle’s displacement from the axis of rotation and the particle’s linear momentum, . For a rigid body, the angular momentum is a product of the object’s moment of inertia, I, and its angular veloci ty, .
Angular period
The time, T, required for a rigid body to complete one revolution.
Angular position
The position of an object according to a co-ordinate system measured in s of the angle of the object from a certain origin axis. Conventionally, this origin axis is the positive x-axis.
Angular velocity
A vector quantity, , that reflects the change of angular displacement with time, and is typically given in units of rad/s. To find the direction of the angular velocity vector, take your right hand and curl your fingers along the particle or body’s direction of rotation. Your thumb then points in the direction of the body’s angular velocity.
Antinode
The points midway between nodes on a standing wave, where the oscillations are largest.
Atom
The building blocks of all matter, atoms are made up of a nucleus consisting of protons and neutrons, and a number of electrons that orbit the nucleus. An electrically neutral atom has as many protons as it has electrons.
Atomic number
A number, Z, associated with the number of protons in the nucleus of an atom. Every element can be defined in s of its atomic number, since every atom of a given element has the same number of protons.
Axis of rotation
The line that every particle in the rotating rigid body circles about.。
