Which of the following best describes Newton’s third law of motion?
For every action, there is an equal and opposite reaction.
Objects in motion tend to stay in motion unless acted upon by an external force.
The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
Energy cannot be created or destroyed, only transformed.
