When a person kicks a wall with a bare foot, he exerts a force of action on the Wall. The same time he himself experiences the force of reaction exerted by the Wall on his foot. These forces have the same magnitude and opposite directions.

 

(2) 

A person, while swimming, pushes the water in the backward direction. At the Same time the experiences an equal (in magnitude) and opposite (in direction) Push in the forward direction, due to the force of reaction of water.

(3) 

When a bat strikes a ball, the ball also exerts an equal (in magnitude) and Opposite (in direction) force of reaction on the bat at the same time. The force on the ball increases its velocity and the force on the bat solves down its followed Motion.

 (4) 

When a bullet is fired from a gun, the gun and the bullet exert forces of action and     Reaction on each other. These forces are equal in magnitude, opposite in direction and arise at the same time. The force on the bullet imparts it high velocity and the Force on the gun makes it receive, i.e., the gun moves in the opposite direction Compound to the gun moves in the opposite direction compound to the velocity of the bullet.

 (5) 

When a book is kept on a table, it exerts downwards force on the table (action). At the same time, the table exerts upward force of the same magnitude on the Book (reaction).
