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

According to Newton's second law, if you increase the force applied to an object :

• it accelerates more
• it doesn't move
• you get more inertia
• it decelerates
