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.
