potential differrence就是初中物理里的电压，potential energy在引力场叫重力势能，一般喜欢用公式mgh表达，但是在电场就叫电势能，也有公式的。总之势能是与物体位置相关的能量。本质原因是力做功导致的
Gravitational potential: gravitationalpotential energy(U) at that location per unit mass. In symbols:V=Um 下面演示下正确思考路径, 考虑某物体m2从∞点拿到某个距离物体m1为r1长度的位置,如下图所示: By convention, Infinity is U=0 which is the point where potential energy is 0. 因为我们有W=F→...

What differences between Gravitational Potential Energy and Potential Energy?如题,中文意思是——势能和重力势能有什么区别?势能=Potential Energy (简称PE)重力势能=Gravitational Potential Energy (简称GPE)根据这个公式:Mechanical energy=potential energy+kinetic energy我想问的是,这里的potential energy是没有计算公...
Confused Difference Electric Electric potential Electric potential energy Energy Potential Potential difference Potential energy In summary, the conversation discusses the differences between electric potential energy, potential difference, and electric potential in layman's terms. It is explained that potential...
potential difference英语定义 "Potential difference" refers to the difference in electrical potential energy between two points in an electrical circuit. It is a measure of the amount of energy that a charge would gain or lose if it were moved from one point to the other. In an electrical ...

This is the electric potential energy per unit charge. V=PEqV=PEq Since PE is proportional toq, the dependence onqcancels. ThusVdoes not depend onq. The change in potential energy ΔPE is crucial, and so we are concerned with the difference in potential or potential difference ΔVbetween tw...
