摘要: 提出用长摆线单摆实现在准水平面内的无摩擦运动,用摄像头记录二维碰撞过程,设计了检验二维碰撞中动量守恒和机械能守恒的教学实验.

关键词: 碰撞, 动量守恒, 二维碰撞

Abstract: By using the camera and pendulums with long ropes,an experiment is designed for teaching conservation of momentum and mechanical energy in two-dimensional collision.

Key words: collision, conservation of momentum, two-dimensional collision
