Sophia: Calculating Rotational Inertia

It's a new spin on acceleration! Watch as visitors at a park try to explain the rotation of the Earth using a granite model. The interviewer demonstrates the application of force in different directions to cause the sphere to accelerate...

It's all about how you pull—not how hard! The 12th installment in a physics series explains the importance of the direction and angle of force when calculating torque. The narrator includes a discussion of the moment of inertia as...

In the following video Paul Andersen explains how the angular momentum of an object if a product of the rotational inertia and the angular velocity. The rotational inertia depends on the mass, radius and shape of the rotating objects. A...
