What does Newton's First Law of Motion state?

• An object in motion stays in motion unless acted upon by an external force.

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

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

• An object at rest will stay at rest unless acted upon by an external force.

Which of the following is an example of Newton's Second Law of Motion?

• A soccer ball remains still until kicked.

• A rocket launches into space.

• A car accelerates faster when more force is applied to the gas pedal.

• A book resting on a table stays at rest.

What is the formula associated with Newton's Second Law of Motion?

• F = ma

• v = d/t

• a = v/t

• p = mv

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

• Objects will remain at rest unless acted upon.

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

• The force acting on an object is equal to its mass times its acceleration.

• An object will accelerate in the direction of the net force.
