Term
 Newton's First Law
Definition
 An object at rest stays at rest;An object in motion stays in motion-- UNTIL acted upon by an outside force.
Term
 Newton's 2nd law
Definition
 Force = mass x acceleration
Term
 Newton's 3rd law
Definition
 For every action there is an equal and opposite reaction.
Term
 Gravity
Definition
 A force between any two objects with mass. Gets weaker with distance.On earth, things are accelerated at a rate of 9.8 meters per second per second.
Term
 Velocity
Definition
 Speed with direction
Term
 Speed
Definition
 Distance divided by time
Term
 Friction
Definition
 A force that opposes motion. Related to mass; roughness or smoothness of the surfaces in contact; surface area touching, etc.
Term
 Physics
Definition
 The study of laws that govern objects in motion. Lots of fun math calculations involved!
Term
 Force
Definition
 A push or pull on an object. (see Newton's 2nd law)
Term
