期末复习选择题练习(一)
期末复习选择题练习(一)一.选择题1.下列说法中正确的是() [单选题] *A.当车从高架桥上通过时,桥面没有发生形变B.当你对一个物体施力时,你一定也受到这个物体对你力的作用(正确答案) C.彼此接触的物体之间一定有力的作用D.只有当物体发生形变时,才能说明它受到了力的作用答案解析:当车从高架桥上通过时,对桥面有压力,桥面会发生形变,故A错误;物体间力的作用是相互的,当你对一个物体施力时,你也会受到物体对你的力,故B正确;彼此接触的物体之间不一定有力的作用,例如将水平面上竖直放置的两个长方体靠在一起,虽然接触,但两物体之间没有力的作用,故C错误;力的作用效果有两个,一是改变物体的形状,二是改变物体的运动状态,所以当物体的运动状态发生改变时,也能说明它受到了力的作用,故D错误。
2.如图所示的现象中,主要说明力可以改变物体形状的是() [单选题] *A.(正确答案)BCD答案解析:小桌将海绵压变形,小桌的压力改变了海绵的形状,故A正确;铁球在磁铁的吸引下运动路径变弯,磁铁对铁球的吸引力使铁球的运动方向发生了改变,属于力改变物体的运动状态,故B错误;守门员接住足球,改变了球的运动状态,故C错误;运动员用力将标枪掷出,改变了标枪的运动状态,故D错误。
3.如图所示,在东京奥运会男子200米混合泳决赛中,中国选手汪顺以1分55秒的成绩成功夺冠!关于游泳过程,下列说法中错误的是()[单选题] *A.汪顺向后划水的力大于水对他的作用力(正确答案)B.汪顺与水之间的作用力是相互的C.使汪顺向前运动的力的施力物体是水D.力改变了汪顺的运动状态答案解析:汪顺游泳过程中,他的手和脚向后划水,对水施加向后的力,由于物体间力的作用是相互的,水就会对手和脚施加向前的反作用力,人就向前运动,所以汪顺向后划水的力和水对汪顺的力是一对相互作用的力,大小相等,故A错误、B 正确;水对汪顺的力使汪顺向前运动,所以施力物体是水,故C正确;水的推力使汪顺向前运动,改变了他的运动状态,故D正确。
