What is Newton's 2nd Law of Motion?

• Action - Reaction. If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.

• F = ma. An object acted on by an unbalanced force will accelerate in the direction of that force, in direct proportion to the strength of the force, and in inverse proportion to the mass of the object.

• Inertia: An object in motion tends to stay in motion, while an object at rest tends to stay at rest unless acted upon by an unbalanced force.
