Term	Definition/description
force	any push or pull that causes an object to move, stop, or change directions
friction	force that opposes, or acts against, motion when two surfaces rub against each other
magnetism	the force of repulsion or attraction between poles of magnets
gravitation	force that pulls all objects in the universe toward one another
balanced forces	forces equal in size and opposite in direction
unbalanced forces	when one force is greater than its opposite force
acceleration	when an object starts to move, speeds up, slows down, stops, or changes direction
net force	combined forces
work	use of a force to move an object through a distance
power	amount of work done for each unit of time
machine	something that makes work seem easier by changing the size or direction of the force
position	an object's place, or location
speed	measure of the distance an object moves in a given amount of time
velocity	an object's speed in a particular direction
acceleration	any change in velocity
momentum	measure of how hard it is to slow down or stop an object
inertia	property of matter that keeps it moving in a straight line or keeps it at rest
Newton's first law of motion	an object at rest will stay at rest, and an object in motion will continue moving in a straight line at a constant speed until an outside force acts on it
Newton's second law of motion	an object's acceleration depends on the size and direction of the force acting on it and on the mass of the object
Newton's third law of motion	For every action, there is an equal and opposite reaction
orbit	the path one body in space takes as it revolves around another body
