Let’s play… Is it Potential Energy or Kinetic Energy? Air coming out of a balloon. STOP AND TALK- TELL YOUR WHAT YOU THINK AND WHY? Let’s play… Is it Potential Energy or Kinetic Energy? Air coming out of a balloon. Answer: Kinetic Energy Let’s play… Is it Potential Energy or...
Kinetic energy vs. Potential energy Energy is the ability to do work. Objects can have stored, or potential, energy when work has been done (such as raising an object in the air) or by virtue of their position (such as sitting at the top of a hill). Potential energy changes to ...
potential energy 势能 kinetic energy 动能 当球抛向高空时、球具有动能、当球向上飞行到顶点时、球的动能就会转化为重力势能、当球向下落时、球的重力势能就会转化为动能、当球刚刚接触地面时、动能就会转化为重力势能、当球接触地面被压扁时、重力势能就会转化为弹性势能、当球从地面弹起的候、弹性势能...
机械能(Mechanical Energy)是物体的动能与势能之和。 -动能(Kinetic Energy, KE):物体运动产生的能量。12mv2 -势能(Potential Energy)是物体由于高度或位置具有的能量。最常见的是重力势能(Gravitational Potential Energy)。 机械能守恒定律指出: 在一个理想系统(无摩擦和空气阻力)中,若只有重力或弹力做功,则系统的...

Simply put, energy is the ability to do work, which is a physics term to describe moving objects with some force across some distance. There are several different forms of energy, and it can be transformed from one form to another.
