Calculate the rotational momentum of a spinning object.

Overview
Angular momentum (L) is a physical quantity that is a measure of the amount of rotation an object has, taking into account its mass, shape, and speed.
💡
Pro Tips
L = I * ω (I = moment of inertia, ω = angular velocity).
Angular momentum is conserved in a system where no external torque acts.
Units: kg·m²/s.

Fun Facts
"Angular momentum is why a spinning bicycle wheel doesn't fall over as easily as a stationary one."
"Ice skaters spin faster by pulling their arms in, which decreases their inertia and increases their angular velocity to conserve momentum."
"Pulsars are neutron stars that spin incredibly fast because they collapsed to a tiny size while conserving the angular momentum of their parent star."
