What is Newton's Third Law of Motion?

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

If a force of 26 N is exerted on two balls, one with a mass of 5 kg and the other with a mass of 10 kg, which ball will have the greater acceleration? (a=F/m)

• The one with a mass of 10 kg will have the greatest acceleration.

• The one with a mass of 5 kg will have the greatest acceleration.

• They will both accelerate at the same rate.
