Gravity
amount of matter in an object
mass
two types of electrical charges
positive and negative
north and south ends of a magnet
Poles
particle (or charge) that moves through an electric circuit
electron (or negative)
two ways to increase gravitational potential energy
increase mass, increase distance
when referring to forces, pushing apart
Repelling
when referring to forces, pulling together
attracting
coil of wire that is magnetized when electric current is run through it
solenoid
path of one object around another in space due to the gravitational force between them
orbit
charged particle that can move between objects
electron (negative charge)
3 types of materials that are always attracted to magnets
iron, cobalt, or nickel
device that is used to store charges in an electrical circuit
capacitor
two factors that affect the amount of gravitational force between objects
distance, mass
two factors that affect the amount of electric force between objects
distance, amount of charge
2 factors that affect the amount of magnetic force between objects
distance, whether materials have magnetic properties
3 factors that affect the strength of electromagnetic force created through a solenoid
number of coils, coil density, voltage/current
