多功能平抛运动实验装置的研制及应用

Development and application of multi-functional horizontal projectile experiment device

利用日常生活用品及磁控和光控开关,研制出操作简单、实验效果明显的多功能平抛运动实验装置,不仅可直观展现平抛运动在水平方向与竖直方向分运动的同步性,还可借助Tracker软件对实验现象进行数据分析验证,解决了传统平抛运动实验装置功能单一、描迹困难及不够精确等问题.

By using daily necessities,magnetic control and optical control switches,a multi-functional horizontal projectile experiment device with simple operation and obvious experimental effect was developed.It could not only visually show the synchronization of horizontal and vertical movement of horizontal projectile motion,but also could analyze and verify the experimental phenomena with the help of Tracker software,which solved the problem in traditional horizontal projectile experiment device such as single function,difficult in tracing and inaccuracy etc.
