What are the Equations for Kinetic Energy and Angular Momentum
of a Point Particle Moving in a Circle? (5:53)
When a point particle is moving along a circle, should we use the translational or rotational kinetic energy equation? Should we use the point particle or rigid object with shape equation for angular momentum? The equations are also determined if the point particle is moving along an ellipse. This is an AP Physics 1 Topic.
