Three laws of motion and cricket

like 172

in this cricket fanatic nation whats better than understanding basic laws of nature using everyones favourite 'cricket'. From virats well timed cover drive to johnsons speed everywhere is physics

First law of motion- A particle in motion or at rest will remain in motion or rest unless there is external unbalanced force. Lets see a seasoned ball will remain at rest unless bowler apply force on it. Similarly we will see when a batsmen hit ball , ball will continue to travel in the direction of hit. ball will only stop when you apply a external force. Ball is stopped when fielders apply force or by frictional force.When we see there is dew in ground there is less friction on ground and ball rushes.

Second law of motion - Rate change of momentum of particle is directly proportional to force applied or mass*accelration = force. Whenever a fielder catches ball we will notice that fielders takes his hands away while catching . While catching if we stop the ball in small time we will have to apply large force to do great momentum of ball. Thus if we stop ball in more time force applied will also be small thus not harming us.

Third law of motion - Every action has equal and opposite reaction. This perhaps most famous law . When a fast bowler comes running and throw the ball he is applying force on ball. Also at same time ball will also apply same magnitude of force though we see much effect. But ask a fast bowler , we will get to know that while bowling they feel strain in muscles. Thats how bowlers face minor injuries. Imagine the force on bowlers hand.

These are my thoughts. Classical mechanics is queen of physics and newtons law of motion are basic rules. Comments are most welcomed.

third law is unproved when a dot ball is delivered i think so

Can third law can be proved for a spin ball

The second law of motion can also be proved in cricket as follows:
When a batsmen hits a six, he swings his bat as fast as possible. The small amount of time indicates the larger acceleration.
Now, F= m*a.
So force aplied will be more. And he successfully hits the shot......
