What is Newton's First Law of Motion?

• Objects in motion stay in motion or an object at rest stays at rest unless acted upon by an external force.

• The acceleration of an object is directly proportional to the net force acting on the object.

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

• The force of gravity is the only force acting on falling objects.

If the net force on a moving object is zero, what can we say about the object's motion?

• The object is accelerating.

• The object is slowing down.

• The object has constant velocity.

• The object is changing direction.

Which of the following is the correct formula for Newton's Second Law?

What is Newton's Third Law?

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

• The bigger mass will always exert a bigger force.

• An object at rest stays at rest.

• Acceleration is due to gravity only.
