Spin and the Magnus effect
- 3 things to know
- Components 1 and 2
Overview
The Magnus force, how spin is created, the flight and bounce of topspin, backspin and sidespin, sidespin in football, tennis topspin and golf backspin, and reading spin to receive a ball.

Questions from this subtopic
Each one with the model answer underneath.
- 1
What is the Magnus force?
Model answer
The Magnus force is the force created by a pressure difference around a spinning ball. The force makes the ball deviate from its expected path.
- 2
How is spin created?
Model answer
Spin is created by applying an eccentric force to a ball, off its centre of mass. The ball then rotates as it travels.
- 3
How does topspin affect a ball's flight?
Model answer
Topspin creates a downward Magnus force. The ball dips quickly in flight.
- 4
How does topspin affect a ball's bounce?
Model answer
A ball with topspin gains speed as it grips the surface. The ball kicks on quickly off the bounce.
- 5
How does backspin affect a ball's flight?
Model answer
Backspin creates an upward Magnus force. The ball stays in the air longer and floats.
- 6
How does backspin affect a ball's bounce?
Model answer
A ball with backspin loses speed as it grips the surface. The ball sits up at a steeper angle and may even check back.
