Potential energy is sometimes called the energy of position. This means that it has the ability (potential) to become kinetic energy. A bowling ball that is held over your head has potential energy....
kinetic is speed and expenditure of energy. Potential is about storing the energy. So if kinetic is speed and potential is about how can you store it. Then the simpliest answer would be to walk up a...
Kinetic energy is the speed of the particles. The faster they move the more kinetic energy they get the hotter they get and there particles spread out.
