law of universal gravatation | states that the force of gravity acts between all objects |
mass | a measure of the amount of matter in an object |
newtons 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 | that rate at wich charges pass through a given point |
potential difference | the potential difference between two location |
voltage | the potential difference between two points |
insulator | a material that dose not conduct heat of electrical energy well |
circut | a closed path though which electricity can flow |
load | a device in a circuit that dose work using electrical energy |
conductor | a material that allows heat or electrical energy to flow through easily |
resistor | an object added to a circuit that restricts the flow of electrical energy |
switch | a device used to control the flow of current through a circuit |
series circut | a circuit in which that 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 samea device that transforms mechanical energy into electrical energy |
magnetic force | the force of attraction of repulsion generated by moving or spinning electric charges |
magnetic feild | area surrounding a magnet in which the magnetic force exists |
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 |
