Every pitcher in the major
leagues is an expert in the Magnus effect event though they may not
know it. Throwing curve balls, knuckle balls and sliders all
result from the Magnus effect.
Should a pitcher want to curve the ball away from the batter he or she
would pitch the ball very fast with a sideways spin rotating towards
batter. The resulting Magnus force pushes the ball away from its
linear trajectory and away from the batter's bat.
The best golfers in the world wouldn't be able to hit a shot over
250 yards without the Magnus effect. The wedged shape of a driver
imparts a spin on the golf ball as it is struck. The driver
forces the ball into a spin (often called backspin) at an impressive
rate of over 4,000 RPM! The dimpled shape of a golf ball also aids in
long range drives by creating less turbulence around the ball while
flying through the air. These two factors, backspin and the
dimpled shape of the ball contribute greatly to the range a golfer can
drive the ball.
Tennis players like Baseball players and golfers use the Magnus effect
to best their opponent. The tennis ball with its high coefficient
of friction about its surface and relatively small mass can be curved
wildly if hit right. In fact, Isaac Newton refined Heinrich
Magnus' theory after watching a Tennis match in 1672. By hitting
the tennis ball at an angle with the racket will impart a spin on the
ball forcing it to change direction during flight.
