Science of Cricket-2: The spin with which Chahal became the highest wicket taker of this IPL season, know the science of that spin bowling

Fast bowlers may create fear in the mind of the batsman with their speed, but the real magician of the ball is said to be spin bowlers. A spinner has bowled the best ball of the century. There are also three spinners in the top five bowlers with the most wickets in cricket history. Even Yuzvendra Chahal, who has so far taken the highest wicket in this season of IPL, is also a spin bowler.

Now you must be thinking that if you wish you could also learn to sp

in the ball, then you would also have a passion for cricket. It may take you time to learn spin bowling, but the science of spin bowling can definitely be learned in a few minutes. In this episode of 'Science of Cricket' series, today we will know the story of ball spin.

Items needed to swing the ball

We will understand the science of spin of the ball in two parts. The movement before eating the first tappa and the movement after eating the second tappa. It is because of these two movements that the ball spins. To understand the science of ball spin, one has to know some terms related to it.

First let us understand what is Revolution? When the ball rotates on its axis, it is called revolution. This revolution is spin. The ball is made to spin in the air in two ways. One top spin and one back spin. In top spin the ball spins forward and in back spin it spins backwards. Its effect is on the place where the ball hits.

The science of the ball spinning before it hits

When the spinner releases the ball from his hand, he releases the ball while spinning it. Meaning the ball keeps rotating on its axis. When the rotating ball is traveling in the air, the Magnus Effect works on it.

Now the question arises that what is this Magnus Effect? When the ball moves forward without rotating, the air around it remains the same, but when the ball is thrown by rotating the ball, the speed of the air around it changes. So the pressure around it changes and the ball starts moving towards the lower pressure. This is the Magnus Effect. The Magnus effect was named after H.G. Magnus, who first discovered this effect during an experiment in 1853.

The tip of the ball is affected due to the Magnus effect.

In the Magnus Effect, when the ball hits the air, the ball's revolution envelops the air on one side and the air on the other side is normally expelled. The side opposite to whichever side the ball envelops the air gets pushed.

In back spin, the ball lands beyond the point it would normally land. Whereas in top spin, the ball lands slightly behind instead of eating the normal tip. Using this, the bowler dodges the batsman in the air.

The science of changing the direction of the ball after being hit

Now let's try to understand why the ball spins when it is eaten. When the ball hits the pitch with revolution, the law of friction is applied to it. According to this law, friction or friction acts only opposite to a moving object. In such a situation, when the revolution of the ball is left to right, then the ball will turn to the left side and if this revolution is from right to left then the ball will rotate to the right. Conventionally these two spins are called leg spin and off spin.

Shane Warne is considered to be the best leg spinner in the world. He has taken 708 wickets in his career.

Leg spinner Shane Warne was considered the magician of the ball. The ball on which Warne took the wicket of Michael Gatting was called 'Ball of the century'. Warne's natural action helped him, so that he threw the ball with more resolution and used the Warne Magnus effect to beat the batsmen in the air. India also has excellent spin bowlers like Anil Kumble, Harbhajan Singh, Ravichandran Ashwin and Yuzvendra Chahal, who can stun the batsmen with their spin.
