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

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 ...
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:...
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?
Although heat and thermal energy are related, there is a difference between the two. Heat describes the transfer of thermal energy in a system, while thermal energy actually measures the state of this heat energy in a system. Thermal energy also deals with properties of heat transfer like condu...
