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
