研究平抛物运动实验成功之关键

The Keys to Success of Test Researching the Metion of Level Projoctile

在研究平抛物运动的实验中,只要注意做好关键的六点,实验就会成功,描出的平抛 物运动轨迹比较准确,求出的初速度误差较小。

The lest researehing the motion of level projectile will succeed, the trajectory of motion of level projectile drawn is relatively, the error of initial velocity calculated out is relatively little, if only the six keys are made.
