“研究平抛物体运动”是中学物理中一个重要的分组实验,求平抛物体的初速度是实验的目的之一.但由于实验操作的不规范,时常没有完整地作出物体运动的轨迹,对求初速度带来困难.本文就实验中可能遇到的几种情况作出分析,供实验参考.
“The study of flat-paned object motion” is an important grouping experiment in middle school physics, and the initial velocity of paraboloid is one of the purposes of the experiment.However, due to the irregular operation of the experiment, the trajectory of the object’s motion is often not completely made , Which will bring difficulties to the initial speed.This paper analyzes several situations that may be encountered in the experiment for the experimental reference.
