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
potential：常用于描述人的能力、事物的可能性或潜在价值，如“每个孩子都有成功的潜力”。prospective：常用于描述未来的状态、关系或角色，如“她嫁给了一个未来的律师”或“她是他未来的岳母”。搭配对象：potential：通常与名词如“potential for success”、“potential energy”等搭配使用。prospective：...
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...
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:...

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.
The chemical potential of the substance forming a nucleus of size greater than critical (after the potential energy barrier has been overcome) is lower than the chemical potential of the substance in the initial phase. This difference in chemical potential is the driving force for the growth of ...
