the science behind the spin bowling in cricket
In: Physics
First, as the ball spins, it is dragging air around it, creating high and low pressure zones on either side of the ball. As air moves from the high pressure to low pressure zone, it pushes the ball in that direction. This is called the [Magnus Effect](https://www.youtube.com/watch?v=23f1jvGUWJs)
More importantly, it adds unpredictability to the bounce. As the ball bounces off the clay, the spin it has will help it dig further into the ground and grip more of the particles. Because the clay has particles of different size and shape, you can’t know how it the ball will bounce off those particles. The idea being something like these [reaction balls](https://www.amazon.com/reaction-ball/b?node=5819910011)
