kinetic energy | energy a moving object has bexasue of its motion deoends on the mass and speed of the object |
joule | SI uint 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 object due to their position above earth's surface depends on the distance above earth's surface and the object 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 |
