What are the similarities and differences between kinetic and potential energy?
What are the similarities and differences between kinetic and potential energy? KE is the energy possessed by an object by virtue of it being in motion. PE is the energy possessed by an object by virtue of its position. It can be transferred from one object to another and this happens during collisions. Potential Energy, […]
