Newton’s Three Laws in Cricket
Cricket is a game of patience and skills. Most of us know how cricket is played but we are unknown with its physical significance. Cricket and Physics go side by side. The rules or the formulae we have been studying until data are highly useful in the field of Cricket. So, we will be talking about three basics laws of motion and its application in Cricket.
1) First Law: Newton’s first law talks about the rest or motion of a body. ” The body continues to be in rest or motion until a certain force is applied in it.” This has a practical application in Cricket. A cricket ball never moves on its own. A certain force has to be applied to bring it in motion. Similarly, a moving ball can’t stop itself. It requires a force that is capable of stopping it. In a similar way, while playing a shot cricketer has to apply an external force which results in the movement of a bat in a particular manner.
2) Second Law: According to the second law, Force is equal to change in momentum per unit time. It talks about the dependency of acceleration upon two factors, net force and the mass of the object.
F= Change in Momentum/ Time
We can clearly say that Force acting on a body is inversely proportional to Time. This is the reason a fielder catching a ball on the cricket field lowers his hands. Lowering hands increases the time of impact, decreasing the acting force. This will decrease the injury or pain in the fielder’s hand. So, in order to catch the ball applying less force, a fielder lowers his hands while catching a cricket ball.
3) Third law: ” To every action, there is an equal and opposite reaction.” Bowling and Batting both follow the third law. Pulling action between the ball and Earth takes place. When a bowler bowls a ball, it is being pulled toward the earth which is the action force while the ball is also pulling the earth towards itself which is a reaction force. Similar is the case with the bat. The bat hitting a ball is the action while the bat being hit by a ball is a reaction. During the delivery of a ball, a person applies a certain force on a ball which can be called an action force. As a result, he experiences sudden pain in his hands, which is a reaction force. When a ball is thrown on the ground, it has an opposite reaction from the ground.
