Question

A curve ball's path bends to the right as it flies towards homeplate because it experiences an aerodynamic force to its right. Onereason the ball is experiencing this aerodynamic lift force is thatthe ball is spinning, and that spin

A)exerts a torque on the ball that causesits angular momentum to shift towards the left.
B)causes the air to flow more rapidly aroundthe right side of the ball than around the left side of theball.
C)exerts a torque on the ball that causes itsangular momentum to shift towards the right.
D)causes the air to flow more rapidly aroundthe left side of the ball than around the right side of theball.

Answer 1

B)

Step-by-step explanation:

This is because the Magnus effect. A traveling spinning ball causes the air on one side to move faster than on the other side, and because, as the Bernoulli equation states, an increase of velocity leads to a decrease in pressure, a force towards that side will appear. Since the ball bends to the right, the air around the right side is flowing more rapidly.
