Chapter 11, Problem 32A
When a bowling ball leaves your hand it may not spin. But farther along the alley it does spin. What produces the spinning?
Expert Solution & Answer
To determine
Spin producing factors
Explanation of Solution
Introduction:
Frictional force is defined as the force that is produced when two object contacts and slides against each other.
When ball leave the palm, it may spin due to friction force (that is caused by air resistance). Spinning of ball is the rotation of the ball about its axis. It is known that for rotational motion, torque is required. So, torque will be produced due to force exerted by the palm of player and friction force. Hence ball will be spinning after it leaves the palm of player.
Conclusion:
Spin produces due to frictional force.
