静电势能(electrostatic potential energy)静电势能是把一个电荷从无穷远处移动到这个位置需要做的功。 静电势能的符号: U 图示: 计算公式: U =\frac{q_1q_2}{4\pi\epsilon_0R} \\其中 U 是静电势能,单位焦耳q…
When a free positive chargeqis accelerated by an electric field, such as shown in Figure 1, it is given kinetic energy. The process is analogous to an object being accelerated by a gravitational field. It is as if the charge is going down an electrical hill where its electric potential ene...
