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 object |
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 two location |
Voltage | The potential difference between two points; measured in volts |
Insulator | A material that does not conduct heat of electrical energy wall; often used to prevent energy from leaving a particular area |
Circut | 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 to flow though 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 |
Magnetic 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 |
