Newton's Laws Review

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
