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 前者是相对于0势能位置的势能，后者是指任意两个位置的势能差
Now the electrical potential difference V A->B is defined as the electrical potential energy divided by the charge. Find the electrical potential difference. What are the units for potential? q U V B A B A electrical potential difference B A B A l d E q l d E J/C=V Elect...
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→...
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是没有计算公式的,至少在我们书上是没有的,所以不可能涉及到,但是GPE是有公式的,GPE=mass·9.8m/s²·height.是不是potential energ...
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...

This chapter illustrates that the electrical force on a charge q leads to electrical potential energy, denoted by U. The amount of electric potential energy equals the product of q and a quantity V called the electrical potential, whose unit is the volt. Just as for gravity, where only ...
