acceleration - a rate of increase of velocity, distance - the space between two places, force - a push or pull upon an object resulting from the object's interaction with another object, friction - force that resists the sliding or rolling of one solid object over another, inertia - the tendency of a body to maintain at rest or in motion, mass - the property of a body that makes it have weight, Newton (N) - unit of force that is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second, Newton's First Law - the law of inertia which states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an outside force, Newton's Second Law - force is equal to the mass of an object times its rate of acceleration, Newton's Third Law  - for every action there is an equal and opposite reaction, speed - distance travelled per unit time, velocity  - the rate or speed of something,
