heat | type of energy that moves from anything having a higher temperature to anything having a lower temperature |
kinetic energy | energy that causes change in the form of motion |
law of conservation of energy | a law stating that energy can change from, bu it cannot be created or destroyed under ordinary conditions |
magma | hot metled rock orignating beneath Earth's surface,; it is a potential source of energy for heating and generating electricity |
mechanical energy | the total kinetic energy and potential energy in a system |
potential energy | energy that is not causing change right now but is stored for potential use |
