What is Newton's Third Law?

• For every action force, there is an equal and opposite reaction force

• The greater the force, the greater the acceleration. The greater the mass, the greater the force needed for the same acceleration

• An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force

• An object changing position

What is Newton's Second Law?

• A push or pull that causes an object to change its motion

• For every action force, there is an equal and opposite reaction force

• The greater the force, the greater the acceleration. The greater the mass, the greater the force needed for the same acceleration

• An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an unbalanced force

What is an example of Newton's Second Law?

• A rocket launching

• Throwing a ball

• Kicking a ball

• Something that stays in motion or at rest.
