Take 5 examples from your surroundings and give explanation based on Newtons Laws of motion?
(1)
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.
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.
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).
