mechanical energy | total amount of kinetic and potential energy in a system |
law of conservation of energy | states that energy may change form but it cannot be created or destroyed under ordinary conditions |
temperature | measure of the average kinetic energy of the particles in a sample of matter |
thermal energy | the total energy of the particles in a material |
heat | thermal energy that flows from something with a higher temperature to something with a lower temperature |
