中考物理必刷02 选择40题(解析版)

2020中考物理总复习满分必刷200题（尖子生专用）满分必刷单项选择题40题1．汽车在平直公路上以速度V0匀速行驶，发动机功率为P0，牵引力为F0，t1时刻开始，司机减小了油门，使汽车保持恒定功率P行驶，到t2时刻，汽车又开始做匀速直线运动，速度为v，已知运动过程中汽车所受阻力f恒定不变，汽车牵引力F随时间变化的图象如图所示，则（）A．t1至t2时间内，汽车做加速运动B．F0＝2fC．t2时刻之后，汽车将保持功率P0行驶D．v＝v0【答案】D【解析】由题知，在t1时刻以前，汽车以速度v0匀速行驶，发动机功率为P0，牵引力为F0，则：P0＝F0v0﹣﹣﹣﹣﹣﹣﹣①；在t1时刻，司机减小了油门，汽车的功率突然减小为P，在该瞬间汽车的速度不变（仍为v0），由图象知牵引力由F0突然减小为F0，所以：P＝F0v0﹣﹣﹣﹣﹣﹣﹣②，由①②可知P＝P0（即汽车的功率突然减小为原来的一半）。

A．由图可知，t1至t2时间内，汽车受到的牵引力增大，功率不变，由P＝Fv可得，汽车行驶的速度减小，所以汽车做减速运动，故A错误；B．汽车做匀速直线运动时，牵引力与阻力平衡，所以F0＝f，故B错误；C．由题可知，t1时刻后汽车的功率保持恒定；由前面分析知，汽车的功率将保持P＝P0不变，故C错误；D．由题知，到t2时刻，汽车又开始做匀速直线运动，速度为v；由图可知，汽车再次做匀速运动时的牵引力与最初做匀速运动的牵引力大小相等，均为F0；根据P＝Fv可得第二次做匀速直线运动时的速度：v＝＝＝＝v0，故D正确；故选：D。

2．如图所示，用细绳吊着一个物块，静止靠在墙壁上。

剪断细绳的同时，用一个由零逐渐增大的水平作用力F压在物块上，墙壁足够高，则物块（）A．运动速度变大B．所受摩擦力变大C．动能先变大后不变D．机械能先减小后不变【答案】D【解析】用细绳吊着一个物块，静止靠在墙壁上，此时重力与拉力是一对平衡力；当剪断细绳时，拉力消失，但同时用一个由零逐渐增大的水平作用力F压在物块上，则木块对墙面产生压力，进而产生沿墙壁向上的摩擦力，且摩擦力随着压力的增大而变大。
