Which of the following best describes Newton's Third Law of Motion?
30
Every object in motion stays in motion unless acted upon by an external force.
Gravity is a force of attraction between any two objects with mass.
The acceleration of an object is directly proportional to the force applied and inversely proportional to its mass.
For every action, there is an equal and opposite reaction.
