A spinning cricket ball in air does not follow a parabolic trajectory?
Question: A spinning cricket ball in air does not follow a parabolic trajectory?
A spinning cricket ball in air does not follow a purely parabolic trajectory due to the effect of the Magnus force.
When a cricket ball is released with backspin or topspin, it experiences a force perpendicular to its velocity, known as the Magnus force. This force is a result of the difference in air pressure on the top and bottom of the spinning ball.
If a cricket ball is released with backspin, the air pressure on the top of the ball is lower than the air pressure on the bottom, resulting in an upward force on the ball. This Magnus force causes the ball to curve downwards less steeply than it would if it were not spinning. Similarly, if the ball is released with topspin, the air pressure on the top of the ball is higher than the air pressure on the bottom, resulting in a downward force on the ball. This Magnus force causes the ball to curve downwards more steeply than it would if it were not spinning.
The combination of the Magnus force and the force due to gravity results in the cricket ball following a curved trajectory instead of a purely parabolic one. The amount of curvature depends on the spin rate, speed of the ball, and the air density, among other factors.
Therefore, a spinning cricket ball in air does not follow a parabolic trajectory but rather a curved path due to the effect of the Magnus force.
