摘 要: 利用视频分析软件Tracker分析皮球在下落弹跳过程中位移和速度的变化情况,并依据分析的实验数据测量重力加速度以及皮球与地面碰撞时的恢复系数. The bounce of rubber ball was researched using the video analysis software Tracker.The change of displacement and velocity of the ball were analyzed.Based on the experimental data,the gravitational acceleration and the coefficient of restitution were measured.
