Expert Answer:

Newton's Third Law of Motion:
"To every action, there is an equal and opposite reaction".

We can apply the third law to many situations:
1. When you stand on the ground, you are actually pushing the ground and the ground is pushing you by an equal force.
2. When you pull a spring with both hands, you feel an equal force trying to pull the spring back.
Thus, action and reaction forces are present. However, the action and reaction forces act on two different bodies.

1. Recoil of a pistol: When a person fires a gun, he gets a push in the backward direction.
2. Swimming: While swimming, a person pushes against the water. The water exerts an equal and opposite force on the person enabling forward movement.
