求翻译：严格按照科技术语来讲，能的两种主要形式通常可分类为势能和动能。动能就是由于物体运动而产生的能量。一只扔出去的足球，一辆飞速行驶的汽车，一条瀑布以及从悬崖上滚下的岩石都能产生动能。一个物体的位置所具有的能量称为势能，势能的形式有很多种，包括重力势能、弹性势能、化学势能以及电势能。是什么意思？

In strict accordance with the terms of science and technology, two main forms of energy can usually be classified as a potential energy and kinetic energy. Kinetic energy is the energy due to motion. A throw of football, a fast-moving car, a waterfall and rocks rolling down from the cliff to produce kinetic energy. Where the energy of a body called the potential energy, there are many forms of potential energy, including the gravitational potential energy, elastic potential energy, chemical potential energy and electrical potential energy.
