|---|---|
| Law Of Universal Gravitation | States that the force of gravity acts between all objects in the universe. |
| Mass | A measure of the amount of matter in an abject. |
| Newton´s First Law Of Motion | States that an object at rest will stay at rest and an object in motion will stay in motion unless an unbalanced force acts on the object. |
| Electric Current | The rate at which charges pass through a given point; measured in amperes. |
| Potential Difference | The difference in potential energy between 2 location. |
| Voltage | The potential difference between 2 points; measured in volts. |
| Insulator | A material that does not conduct heat of electrical energy well; often used to prevent energy from leaving a particular area. |
| Circuit | A closed path through which electricity can flow. |
| Load | A device in a circuit that does work using electrical energy. |
| Conductor | A material that allows heat or electrical energy to flow through out it easily |
| Resistor | An object added to a circuit that restricts the flow of electrical energy; inhibits the flow of electric current by producing a voltage drop when current passes through it. |
| Switch | A device used to control the flow of current through a circuit. |
| Series Circuit | A circuit in which the parts are joined one after another such that the current in each part is the same. |
| Parallel Circuit | A circuit in which the parts are joined in branches such that the potential difference across each part is the same. |
| Magnetic Force | The force of attraction of repulsion generated by moving or spinning electric charges. |
| Magnaetic Field | Area surrounding a magnet in which the magnetic force exist. |
| Electromagnetism | The Interaction between electricity and magnetism. |
| Electromagnet | A coil that has a soft iron core and that acts as a magnet when an electric current is in the coil. |
| Electric Motor | A device that converts electrical energy into mechanical energy. |
| Generator | A device that transforms mechanical energy into electrical energy. |
