vocabulary for energy unit
| Term | Definition |
|---|---|
| Thermal Energy | The energy that comes from heat, generated by the movement of tiny particles. |
| Mechanical Energy | Kinetic or potential energy associated with the motion or position of an object. |
| Electrical Energy | Energy carried by an electrical current |
| Electromagnetic Energy | the energy of light and other forms of radiation |
| Electromagnetic Waves | A wave of vibrating electric and magnetic fields |
| Equilibrium | state of balance between opposing forces or actions so one is not stronger than another. |
| Conduction | transfer of heat from a warmer substance to a cooler substance through direct contact. |
| Convection | movement in a gas or liquid in which the warmer parts move up and the colder parts move down. |
| Radiation | energy that comes from a source in the form of waves or rays you cannot see. |
| Thermal Expansion | the tendency for something to get larger when heat is added to it. |
| Thermal Contraction | the tendency for something to get smaller when heat is taken away. |
| Conductor | a substance that conducts heat readily. |
| Insulator | a substance that does not transfer heat very well. |
| Thermal Equilibrium | the point at which two objects that are touching reach the same temperature. |
| Thermal Energy Transfer | thermal energy is transferred through a material by the collision of atoms within the material. |
| Mechanical Energy Transfer | when objects push or pull on each other. |
| Electromagnetic Waves | can transmit energy though matter or empty space. |
| Electrical Energy Transfer | when an electrical source is connected in a complete circuit to an electrical device. |
| Energy | the ability to do work |
| Kinetic Energy | the energy of motion |
| temperature | the measure of how hot or cold something is |
| heat | the transfer of thermal energy between objects that are different temperatures (the flow of energy from one material to another.) |
