What is Physics?
Physics expands our life , you can find it
in the water in the sky or on the earth .
it's much important as air and water.
Without we can’t live or life was not
possible. Any thing we do in that physics is
involved, whether we eat or play. Physics
plays an crucial or very important part
in our life.
It’s a subject which teach the principle
behind what we do daily in our life.
So, how physics is related to our
daily life ?

Physics In Daily Life
Physics is related to our life in many ways, Some
of the common example are as follow:
 When we walk or run, our motion is part of
laws of mechanics
 We eat food which undergoes chemical
reactions producing heat energy which is
converted into mechanical energy
 Use of refrigerator, pressure cookers, washing
machines, television, music system, computers,
etc. are all designed on the principles of
physics.
 When we speak, we produce sound properties
of which like pitch and intensity are studied in
physics

Some more examples how physics is related to
our life are as follow:
Electricity that we use in household is a gift
of physics
Automobiles design is based on physics
The list is endless
But there is one very good example of how
physics is related to our daily life that is
Cricket.
Now while playing cricket, How is physics is
related to our life?

Physics In Daily Life
Almost Every one in India play cricket whether rich or
poor, Children or an old person, girl or boy all play
cricket.
Now, is cricket is related to physics ?
Yes, Cricket is related to physics because of following
reason:
Force can change anything of a object like shape,
direction, etc. but force can’t change mass of an
object. In cricket bowler through the bowl and the
batsman with the help of bat apply force on ball and
change the direction.
When fielder through the bowl in air so the transfer
of energy take place from kinetic to potential and to
kinetic energy take place.

A good cricketer always do “follows through” with
the bat, so the force applied for longer time, the
impulse is greater and so also is the gain of momentum
(and Velocity) of the ball.
Batsman ‘following Through’ after
hitting the ball

Almost all cricketer draw back the ball while
catching because to stop a moving ball, its momentum
has to be reduced to zero. AN impulse is then required
in form of an opposite force acting for a certain time.
While any number of combination of force and time
will give particular impulse, the ‘sting’ can be removed
from catch by drawing back the hands as the ball is
caught.
There are many
more points how
cricket is related
to physics.
