gravitational potential energy
... Springs and rubber bands store potential energy that can be transformed into kinetic energy. The spring force is not constant as an object is pushed or pulled. The motion of the mass is not constant-acceleration motion, and therefore we cannot use our old kinematics equations. One way to ana ...
