inertia - When an object doesn't want to change its motion, Newton's 1st Law - An object in motion will stay in motion unless an outside force acts on it, force - a push or pull on an object, motion - change in position, acceleration - the rate at quick an object's motion changes, Newton's 2nd Law - An object's acceleration depends on its mass and on the net force acting on it., Newton's 3rd Law - For every action there is an equal and opposite reaction, speed - distance divided by time, mass - the amount of matter in an object, gravity - the invisible force that pulls object together (such as towards earth), air resistance - force that opposes the motion of objects that move through the air, weight - the measure of gravity on an object, balanced forces - equal forces acting on an object that DO NOT cause movement, unbalanced forces - forces acting on an object that cause a change in movement, friction - the resistance that one surface or object encounters when moving over another., potential energy - energy an object has before moving, kinetic energy - moving energy,
