Kinetic energy vs. Potential energy Energy is the ability to do work. Objects can have stored, or potential, energy when work has been done (such as raising an object in the air) or by virtue of their position (such as sitting at the top of a hill). Potential energy changes to ...
Kinetic Energy and Potential Energy(1)Kinetic Energy Energy can exist in many forms: heat, light, nuclear energy, chemical energy (from food or fuel), stored (potential) energy (such as the energy stored in a compressed spring) and so on. Energy can be transferred from one form to ...
