To prevent it from tumbling in flight, a projectile such as a football is sent off spinning. The physical principle involved is
A) conservation of energy.
B) conservation of linear momentum.
C) conservation of angular momentum.
D) the first law of motion.

Question

Quizplus · Accepted Answer

Conservation of angular momentum is the physical principle involved. As the football spins, its angular momentum remains constant in the absence of external torques. This helps stabilize its motion and prevent it from tumbling in flight.
