Term | Definition |
---|---|
Energy | The capacity to work. |
Work | The transfer of energy to an object by using a force that causes the object to move in the direction of the force |
Kinetic Energy | The energy of an object that is due to the object's motion. |
Potential Energy | The energy that an object has because of the position, shape, or condition of the object. |
Mechanical Energy | The amount of work an object can do because of the object's kinetic and potential energies. |
Thermal Energy | The kinetic energy of a substance's atoms. |
Heat | The energy transferred between objects that are at different temperatures. |
Chemical Energy | The energy that is stored in chemical bonds. |
Electrical Energy | The energy that results from the flow of moving charges. |
Electromagnetic Energy | Energy resulting from the motion of the charged particles within atoms. |
Sound Energy | Energy given off by a vibrating object. |
Nuclear Energy | The energy stored in the nucleus of an atom as a result of a strong nuclear forces. |
Nuclear Fission | The splitting of the nucleus of a large atom to two or more fragments; releases additional neutrons and energy. |
Nuclear Fusion | The combination of the nuclei of small atoms to form a larger nucleus; releases energy. |
Temperature | A measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles of an object. |
Conduction | The transfer of heat by direct contact of particles. |
Convection | The transfer of thermal energy by the circulation of movement of a liquid or a gas. |
Radiation | The transfer of energy as electromagnetic waves. |
