Term	Definition
Newton's 1st Law	an object at rest will remain at rest, and an object moving at a constant velocity, unless acted opon by an unbalanced force.
Newton's 2nd Law	the greater the mass, the greater the inertia
force =	mass x acceleration
acceleration =	net force / mass
measured in	Newtons (N)
Newton's 3rd Law	for every action, there is an equal and opposite reaction
gravity	a force that pulls objects toward each other
if you increase the force on an object, its acceleration	decreases
if you increase the mass on an object, its acceleration	stays the same
a resistance to a change in motion is	inertia
the amount of inertia an object has depends on its	mass
inertia	the tendancy of an object to resist a change in motion
speed =	distance / time
steeper slope =	faster acceleration
gravity =	1. mass 2. distance
what is the name given to the force exerted by the first object on a second object?	reaction force
what is the name often given to the force exerted by the second object back on the first object?	action force
the action and reaction forces in any situation will always be	equal and opposite
the product of an object's mass and veloctiy is its	momentum
momentum =	mass x velocity
the unit of measurment for momentum	kg x m/s
law of conservation of momentum	in the absence of outside forces, the total momentum of objects that interact does not change.
another name for Newton's 1st Law	the law of inertia
what forces cause an object to accelerate	unbalanced forces
acceleration depends on	force and mass
reactions always go in the ... direction of the action	opposite
an action and its reaction are equal in	size
Newton's 3rd Law explains what happens when two objects	interact
forces always come in pairs so each ... has a reaction	action
the force of an action sends a reaction in the opposite	direction
