• The heavy one
• The light one
• They are equal
• There is no such thing as force 

What is Newton's First Law of Motion?

• F = m x a
• Every action has an equal an opposite reaction
• An object at rests stays, an object in motion stays in motion until acted on by an unbalanced force.

A _______ is a push or pull.

• Newton
• Acceleration
• Momentum
• Force

What is Newton's Second Law of Motion?

• F = m x a
• For every action there is an equal but opposite reaction.

• Object in motion will stay in motion, object at rest will stay at rest unless acted on by an unbalanced force.
