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 energy is converted to kinetic energy. Let us explore the work done on a chargeqby the...
The potential energy function without external electric field is fitted by Morse potential, and the fitting parameters are obtained which are in good agreement with experimental values. In order to obtain the critical dissociation electric parameter, the dipole approximation is adopted to construct a ...
potential difference 是指电势差，SAT物理中用V表示，也就是电压。capacitor是电容器，是用来储存电荷的，它储存电荷的能力用电容表示，符号是C。电荷量用符号Q表示，也就是电容器在充电过程中储存的电荷量。stored potential energy 就是指电能，SAT物理里用符号U表示。关于电容器，物理中有几个重要的...

Electric potential is a scalar quantity that describes the potential energy of a charge placed in an electric field, while electric field is a vector quantity that describes the force experienced by a charge in an electric field. Electric potential is dependent on the position in the field...
Potential energyisenergyheld by an object that has yet to be released. Potential energy is often due to an object's height in a gravity field, electric charge, or stresses within the object. It is often referred to as "stored energy" or classified by its type. ...
