Spin in Table Tennis/ Ping-Pong - How Does it Work and How do You Create it?

The diagram above shows what will happen when the direction the rubber surface is travelling is in between the center and the edge of the ball. The closer the line to the edge of the ball, more spin will be given and less speed , and the closer the line to the center of the ball, more speed will be given and less spin.

This means that for the same amount of bat speed, you can generate completely different amounts of spin and speed, just by varying the way you contact the ball.
