When discussing newton’s laws of motion, which terms do people most likely use when talking about newton’s third law of motion?

“force” and “acceleration”
“inertia” and “force”
“action” and “reaction”
“mass” and “inertia”

The answer would be "action" and "reaction".

so C is the answer.

The correct answer to the question is C). Action and reaction

EXPLANATION:

Newton had postulated three laws regarding the motion of a body in an inertial frame.

The first law gives an idea about the qualitative definition of force, and explains the motion of a body with respect to its inertia.

Newton's second law gives the quantitative definition of force. As per Newton's second law, the net external force acting on a body is equal to the product of mass with acceleration.

As per Newton's third law of motion; for every action, there is an equal and opposite reaction.

When a body A applies some amount of force on body B, then the force exerted by body A is called action. The body B will apply same amount of force to the body A in return which is known as reaction.

Hence, people use the terms action and reaction when they discuss about Newton's third laws of motion.
