Kinetic Energy | energy a moving object has because of its motion depends on the mass and speed of the object. |
joule | SI unit of energy |
potential energy | Stored energy an object has due to its position. |
elastic potential energy | energy stored when an object is compressed or stretched |
chemical potential energy | energy stored in chemical bonds |
gravitational potential energy | energy stored by objects due to their position above earth's surface depends on the distance above earth's surface and the object's mass |
mechanical energy | sum of the potential energy and kinetic energy in a system |
Law of conservation of energy | states that energy can never be created or destroyed. |
