| chemical energy | stored in and released from the bonds between atoms |
| electric energy | in an electric current |
| energy | ability to cause change |
| kinetic energy | energy due to motion |
| mechanical energy | sum of potential energy and kinetic energy in a system |
| nuclear energy | stored in and released from the nucleus of an atom |
| potential energy | stored energy due to the interaction between objects or particles |
| radiant energy | carried by electromagnetic waves |
| sound energy | carried by sound waves |
| thermal energy | sum of kinetic energy and potential energy of the particles that make up an object |
| wave | disturbance that transfers energy from one place to another without transferring matter |
| closed system | does not exchange matter or energy with the environment |
| energy transfer | process of energy moving from one object to another without changing form |
| energy transformation | process in which one form of energy is converted to another form of energy |
| law of conservation of energy | states that energy can be transformed from one form to another, but it cannot be created or destroyed |
| open system | exchanges matter or energy with the environment |
| nonrenewable energy | resource available in limited amounts or is used faster than it can be replaced in nature |
| renewable energy | resource is replaced as fast as, or faster than, it is used |
| work | transfer of energy that occurs when a force makes an object move in the direction of the force while |
| conduction | transfer of thermal energy by collisions between particles in matter |
| convection | transfer of thermal energy by the movement of particles from one part of a material to another |
| heat | movement of thermal energy from a region of higher temperature to a region of lower temperature |
| radiation | transfer of thermal energy by electromagnetic waves |
| temperature | measure of the average kinetic energy of the particles in a material |
| thermal conductor | material in which thermal energy moves quickly |
| thermal insulator | material in which thermal energy moves slowly |
| vaporization | change of state from a liquid to a gas |
