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
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...
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→⋅s→⇒dW=F→⋅ds...

Determine electric potential energy given potential difference and amount of charge. Figure 1. A charge accelerated by an electric field is analogous to a mass going down a hill. In both cases potential energy is converted to another form. Work is done by a force, but since this force is ...
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...
求问各位博士大佬,电..求问各位博士大佬,电势差(potential difference)=voltage和能量(energy)的关系. 萌新不懂 随便镇楼没人吗?
Answer to: Explain the difference between potential energy and kinetic energy. By signing up, you'll get thousands of step-by-step solutions to...
The electric potential energy is a form of potential possed by a charged object by the virtue of its position in an electric field. In order to move a charged object from one point to another in an electric field without changing its kinetic energy, work must be done on the ob...
根据这个公式:(((Mechanical energy=potential energy+kinetic energy))这句话是重点我想问的是,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 energy在这里用GPE来代替用来运算呢? 相关知识点: 试题来源:...
