Energy and Matter
Interactions of Energy and Matter
| Term | Definition |
|---|---|
| Energy transformation | The process of changing energy from one form to another |
| Thermal Energy | Energy that is generated by a source and measured by heat |
| Conduction | The movement of heat or electricity through matter |
| Convection | The transfer of thermal energy through a fluid (gas or liquid) |
| Radiation | Energy transmitted in waves or a stream of particles |
| Magnetic Forces | The attractive and repulsive forces between two poles |
| Electric Forces | Occur when ions create attractive and repulsive forces |
| Electromagnetism | A force combining both electric and magnetic forces |
| Conductor | material that transfers energy quickly. |
| Insulator | material that does not transfer energy easily |
| Electricity | is the flow of an electric charge |
| Electrical Current | the flow of electrical energy in a circuit. |
| Circuit | a loop of materials that allows an electrical current to flow. It has no beginning or end |
| Load (Circuits) | The device that changes the electrical energy into another form of energy like light, sound, heat, or motion |
| Open Circuit | The path is incomplete. Electrical current will not flow through the circuit |
| Closed Circuit | The path is complete. Electrical current flows through the circuit |
| Complete Circuit | an uninterrupted path for electrons to flow from an energy source (i.e. battery or household power), through a device and back to the source |
| Series Circuit | all components are connected end-to-end to form a single path for current flow. |
| Parallel Circuit | an electrical path that branches so that the current divides and only part of it flows through any branch. |
| Electric Field | the area around an electric charge that experiences the force exerted by the electric charge |
| Generator | an electric machine that converts mechanical energy into electrical energy |
| Static Electricity | a stationary electric charge, typically produced by friction, which causes sparks or crackling or the attraction of dust or hair. |
| Electrons | Negatively charged subatomic particle |
| Induction | The process of generating current in a conductor by placing it in a changing magnetic field |
| Friction | a force, the resistance of motion when one object rubs against another |
