Angular Momentum

Mr. Andersen explains angular momentum, a vector quantity related to rotating objects. He covers the calculation of angular momentum for both point and extended objects, using formulas involving radius, mass, velocity, and rotational inertia. The video also discusses the role of torque in changing angular momentum and demonstrates practical applications using a turntable and photogate. Key concepts include the right-hand rule for direction and the conservation of angular momentum in collisions.

Explain how angular momentum differs from linear momentum.
