Energy comes in many forms, kinetic, potential (stored), heat, etc. Energy is always conserved. It is not created or destroyed but is just transformed from one form to another.
Kinetic and Potential Energy:
Throwing a ball into the air represents a situation in which the total energy is fixed and there is a continous transformation from kinetic energy to potential energy.
Kinetic Energy = Energy Associated with Motion
Potential Energy --> object has a position in a force field
