高中物理力学中涉及两个守恒定律,即动量守恒定律和机械能守恒定律,掌握了这两个守恒定律,便会对物理概念和物理规律的理解有新的飞跃.这两个定律表示了机械运动的不同本质的规律,有其相似和相异之处.
In high school physics and mechanics two conservation laws are involved, namely the law of conservation of momentum and the law of conservation of mechanical energy. Mastering these two laws of conservation will lead to a new leap in the understanding of physical and physical laws. These two laws represent mechanical motion. The laws of different natures have their similarities and differences.
