What is Newton's first law?
an object at rest will remain at rest and an object in motion will remain in motion unless it is acted on by an unbalanced force.
the acceleration of an object equals the net force acting on the object divided by the object’s mass.
every action has an equal and opposite reaction. This means that forces always act in pairs
What is Newton's second law?
an object at rest will remain at rest and an object in motion will remain in motion unless it is acted on by an unbalanced force.
the acceleration of an object equals the net force acting on the object divided by the object’s mass.
every action has an equal and opposite reaction. This means that forces always act in pairs
What is Newton's third law?
an object at rest will remain at rest and an object in motion will remain in motion unless it is acted on by an unbalanced force.
the acceleration of an object equals the net force acting on the object divided by the object’s mass.
every action has an equal and opposite reaction. This means that forces always act in pairs

Tony has a mass of 50 kg, and his friend Sam has a mass of 45 kg. Assume that both friends push off on their rollerblades with the same force. Explain which boy will have greater acceleration.
Tony will have greater acceleration for a given amount of force.
Sam will have greater acceleration for a given amount of force.
Sam will have greater acceleration due to greater mass.
Tony will have greater acceleration due to greater velocity.
