This equation computes the displacement of an object in flight due to the Magnus force on a spinning object (such as a football, baseball, or soccer ball).
The effect of the Magnus force is commonly observed when a spinning ball (or cylinder) curves away from its flight trajectory. It is important in its use with sports balls to effect a curve over the course of the ball's flight and it must be considered in the trajectory of a spinning missile.1
Examples
For a typical curve ball thrown by a professional baseball player, we might use the following as inputs:
m (mass) = 0.145 kg
L (distance from pitcher to plate) = 18 m
`omega` (spin rate) = 2000 rpm
K (mass parameter) = 5.5 x 10-4 kg
and for this baseball curve example the deflection distance will be approximately d = 0.57 m2
