Which of the following best demonstrates Newton's Third Law?

A) The harder you kick a soccer ball, the faster it accelerates

B) An object sitting on the ground will stay there until somebody or something pushes it

C) Wearing a seatbelt prevents you from continuing to move when the car has stopped

D) When you walk your foot pushes down on the ground while the ground pushes back on your foot

D) When you walk your foot pushes down on the ground while the ground pushes back on your foot

Explanation:

Newton's Third Law states that for every action, there is an equal and opposite reaction. This is actually explains that forces come in pairs and forces are an interaction between two objects. As per the correct option given in the question explains Newton's Third Law.

When you walk your foot (say object A) pushes down on the ground while the ground (say object Q) pushes back on your foot with the same force but in the opposite direction.

The best demostration that applies to Newton's Third Law of motion would be D) When you walk your foot pushes down on the ground while the ground pushes back on your foot.
