Newtons Warm up

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

• An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

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

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

• The force of gravity acts between all masses.

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

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

• A book resting on a table

• A rocket launching into space

• A car accelerating on a highway

• A ball rolling down a hill
