At Rest The state of an object when it is not in motion
Unbalanced Forces Forces on an object that cause change in the motion of the object
Newton’s Second Law of Motion Acceleration of an object depends on the object's mass and the magnitude of the force acting upon it (F = ma). This is often referred to as Newton's law of force and acceleration.
Force A push or pull that can change the motion of an object
Magnitude The size or quantity of something
Acceleration The rate of change in an object's speed
Newton’s Third Law of Motion For every action there is an equal and opposite reaction. This is often referred to as Newton's law of action-reaction.
Action The way that something causes a change
Reaction Resistance or force of equal magnitude acting in the opposite direction of an action force
