动量和能量是高中物理力学部分的又一重要内容 .高中物理力学部分涉及了冲量、动量、动能、重力势能、弹性势能及机械能等概念 ,讨论了动量定理、动量守恒定律、动能定理、机械能守恒定律等规律 .现实世界中涉及动量和能量的问题比比皆是 .例如 :跳绳、跳远、跳高、蹦极等体育
Momentum and energy are another important part of high school physics and mechanics. The physics and mechanics of high school involves the concepts of impulse, momentum, kinetic energy, potential energy, elastic potential energy and mechanical energy. The theorem of momentum, law of conservation of momentum, kinetic energy theorem and conservation of mechanical energy are discussed. Laws and other laws. The problems involving momentum and energy abound in the real world. For example: skipping ropes, long jumps, high jumps, bungee jumping and other sports.
