一、能量的形式一切物体都具有能量,能量是物理学的基本概念,对应物质的各种运动形式,能量有各种不同的形式.初中阶段我们主要接触到的是以下几种能量:机械能:机械能是动能与势能的总和.动能:物体由于运动而具有的能,一切运动的物体都具有动能.势能分为重力势能和弹性势能.重力势能:物体由于被举高而具有的能;弹性势能:物体由于发生形变而具有
First, the form of energy All objects have energy, energy is the basic concept of physics, corresponding to the various forms of physical movement, energy has a variety of different forms of junior high school we are mainly exposed to the following types of energy: Mechanical energy: Mechanical energy is the sum of kinetic energy and potential energy.Kinetic energy: all the objects have the kinetic energy due to the movement, and all the moving objects have the kinetic energy.The potential energy is divided into the gravitational potential energy and the elastic potential energy Gravity potential energy: the energy that the object has as a result of being lifted; : Object has deformation due to deformation
