Forces and Motion
physical science
| Term | Definition |
|---|---|
| Force | push or pull |
| Work | energy that causes a change in motion |
| Law of Conservation of Energy | Energy cannot be created or destroyed, it can only transform |
| Potential Energy | the stored energy due to position |
| Kinetic Energy | the energy of motion |
| Elastic Potential Energy | stored energy that is compressed and/or stretched |
| Gravitational Potential Energy | the stored energy due to height |
| Mechanical Energy | the sum of potential and kinetic energy |
| Newton | the measurement of force |
| Heat | thermal energy moving from a region of higher temperature to a region of lower temperature |
| Friction | the thermal energy due to objects rubbing together. |
| Waste Energy | energy not being used |
| Thermal Equilibrium | Two objects at the same temperature |
| Conduction | the transfer of thermal energy due to collisions between particles in matter. |
| Thermal conductor | a material in which thermal energy moves quickly, such as metals |
| Thermal insulator | a material in which thermal energy moves slowly, such as air |
| Convection | the transfer of thermal energy by the movement of particles from one part of a material to another. (hot rising and cold sinking) |
| Radiation | the transfer of thermal energy from one object to another by electromagnetic waves. |
| Sound energy | requires a medium (vibrating objects), cannot travel through a vacuum |
| Nuclear energy | stored and released in the nucleus of an atom |
