Energy
| Term | Definition |
|---|---|
| Chemical energy | Energy stored in substances (like food, batteries, or fuel) |
| Energy | The ability to do work or cause change. |
| Mechanical energy | Energy of motion and position (moving objects or stored energy in objects). |
| Atoms | Tiny building blocks that make up all matter. |
| Molecules | Groups of atoms joined together. |
| Kinetic Energy | Energy of motion (anything moving has it). |
| Potential Energy | Stored energy (energy waiting to be used) |
| Transfer | Moving energy from one place or object to another. |
| Battery | A device that stores chemical energy and changes it into electrical energy. |
| Complete Circuit | A closed path that allows electricity to flow. |
| Electric Current | The flow of electric charge (electricity moving). |
| Electrical Circuit | A path through which electricity flows. |
| Static Electricity | A buildup of electric charges that stay in one place. |
| Insulator | A material that does NOT allow energy (like electricity or heat) to pass through easily. |
| Conductor | A material that allows energy (like electricity or heat) to pass through easily. |
| Thermal Energy | Heat energy (energy related to temperature). |
| Electric Energy | Energy from moving electric charges. |
| Conduct | To allow heat or electricity to pass through. |
| Insulate | To stop or slow down heat or electricity from passing through. |
| Sound Energy | Energy produced by vibrations that travel through matter. |
| Light Energy | Energy that we can see; travels as waves. |
| Reflect | To bounce light off a surface. |
| Refract | To bend light when it passes through different materials. |
| Absorb (light) | To take in light energy instead of reflecting it. |
| Work | When a force moves an object over a distance. |
| Friction | A force that slows objects down when they rub together. |
| Conduction (heat) | Heat transfer through direct contact. |
| Convection (heat) | Heat transfer through movement of liquids or gases. |
| Radiation (heat) | Heat transfer through waves (no contact needed, like from the sun). |
| Pitch (sound) | How high or low a sound is. |
| Closed Circuit | A circuit where electricity can flow (same as complete circuit). |
| Open Circuit | A broken circuit where electricity cannot flow. |
| Energy Transformation | When energy changes from one form to another (like battery → light). |
| Law of Conservation of Energy | Energy cannot be created or destroyed only transferred or changed. |
