动能、重力势能、弹性势能都具有两个特性:储存性和相对性.了解这两个特性,对机械能的掌握理解具有一定的帮助. 一储存性“物体能够做功,它就具有能量.”、“能够做功不一定非要做出来,它可以储存在那里。”物体的动能可以储存在它的速度中,如果物体的速度不变,它的动能就不变,它也不对
Kinetic energy, gravitational potential energy, and elastic potential energy have two characteristics: storage and relativity. It is helpful to understand these two characteristics to grasp the understanding of mechanical energy. A storage “object can do work, it has energy.” “The ability to do work does not have to be done. It can be stored there.” The kinetic energy of an object can be stored in its speed. If the speed of an object is constant, its kinetic energy will not change, nor will it be correct.
