| 摘 要： | 在气垫导轨上研究了变质量物体在变力作用下的运动规律.利用在滑块上放置载水装置实现质量的减少,通过质量均匀的刚性绳改变作用在滑块上的力,有固定在导轨上的4个光电门获得滑块的位移及速度.本实验结果与理论推导符合较好.

| Abstract: | The motion of variable mass system under variable force is studied using air track.A rider filled with water is used as a variable mass system,a rigid strong string with uniform mass density is used to change the force applied on the rider.The displacement and velocity of the rider is obtained by four photoswitches placed on the air track.The experimental results are found to be in good accordance with the theoretical results. |
