Which of the following best describes Newton's First Law of Motion?

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

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

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

• The force of gravity acts on all objects equally

Newton's Second Law of Motion is represented by which equation?

What does Newton's Third Law of Motion state?

• An object in motion will stay in motion

• The acceleration of an object is proportional to the net force

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

• The force of gravity is constant
