Potential energy is energy that is stored for example a wind up toy, it has energy but in order for you to get kinetic energy, it has to move. So kinetic energy is moving energy.
The difference is that potential is stored and kinetic is moving energy.
<u>Potential energy is</u> the stored energy in an object or thing, while <u>kinetic energy is</u> the energy which an object contains because of a particular motion.
