In all of the following sports, law of conservation of angular momentum is used EXCEPT in
Correct answer: C. Horse riding.
- A. Ice-skating.
- B. Gymnastics.
- C. Horse riding.
- D. Board diving.
Explanation
The correct answer isHorse riding.In horse riding, the primary focus is on the rider's balance, posture, and control over the horse, rather than on performing rotational movements. The law of conservation of angular momentum applies in sports where athletes perform rotations, such as ice-skating, gymnastics, and board diving, which involve spins, flips, and twists. In these sports, athletes manipulate their body position to conserve angular momentum and control their rotational speed.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
