What is Newton's Third Law?

• Object in motion stays in motion and an object at rest stays at rest unless acted on by a outside force
• Force = mass x acceleration
• For every action there is an equal and opposite reaction

What happens when unbalanced forces act on an object at rest?

• the object remains at rest
• the object begins moving in an unpredictable direction
• the object begins moving in the direction of the net force
• the object begins moving opposite to the direction of net force
