Front

If a particle's mass is doubled while keeping speed and radius constant, how does its angular momentum change?

Back

It becomes 2L.

Front

Define angular momentum in the context of circular motion.

Back

Angular momentum (L) is the product of the moment of inertia and angular velocity.

Front

What is the formula for calculating angular momentum?

Back

L = mvr, where m is mass, v is linear velocity, and r is radius.
