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
The potential difference between points A and B,VB–VA, is defined to be the change in potential energy of a chargeqmoved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. 1V=1JC1V=1JC The famili...
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...
The meaning of POTENTIAL DIFFERENCE is the difference in potential between two points that represents the work involved or the energy released in the transfer of a unit quantity of electricity from one point to the other.
引力场计算中的potential和potential energy的表达式中的符号问题总是大家搞不明白的地方,这个其实大家熟知的定义有关系,下面给大家梳理一下正确的思考路径供大家参考。 首先严格的potential的定义是需要我们明确的,这是必须搞清楚的地方且不能存在争议的地方。
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:...

Electric potential is one of the most commonly used electrical quantities and is fundamental to the storage and release of electrical energy. An electron microscope uses a high electric potential difference to accelerate electrons in a beam that bombards the sample under examination. These electrons ...
The meaning of POTENTIAL ENERGY is the energy that a piece of matter has because of its position or nature or because of the arrangement of parts.
