动量定理应用例析

Some Analyses on Application of the Theorem of Momentum

动量与动量定理是高中物理教学的重点之一。动量定理在处理变质量、连续质量、变力作用过程等复杂问题中均可收事半功倍之效。

The momentum and the theorem of momentum is one of key in the physics teaching of senior middle school. The momentum theorem changes the quality, the continual quality in processing, changes the action of force process and so on in the complex question to be possible to receive the twice the result with half the effort effect.
