Final answer:
Inward rotation of a hook ball in bowling is achieved through a proper release. Friction and the oil pattern on the lane play a role in causing the ball to curve. It is similar to the spinning motion of a top.
Step-by-step explanation:
Inward rotation of a hook ball in bowling is achieved through a proper release. When the ball is released, the bowler imparts a spin on it, causing it to rotate on its axis as it travels down the lane.
This inwards rotation of the hook ball is due to the friction between the ball, the lane, and the oil pattern on the lane. The friction generates a force that causes the ball to curve towards the pocket, enhancing its chances of knocking down more pins.
Think of it like a spinning top: when you spin a top on a surface, it stays upright and rotates in a circular motion. Similarly, the release of the hook ball with inward rotation allows it to maintain stability while curving towards the pins.
