Conservation of Angular Momentum
In this video Paul Andersen explains that the angular momentum of a system will be conserved as long as there is no net external torque. Both point objects and extended objects are covered along with several examples.

Kinetic Energy
In this video Paul Andersen explains how the kinetic energy of an object if due to the motion of an object. Objects can have kinetic energy but they cannot have potential energy unless they are part of a system. He then explains how to...

Rotational Inertia
In this 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 sample...

TED-Ed: The physics of the "hardest move" in ballet - Arleen Sugano
In the third act of "Swan Lake", the Black Swan pulls off a seemingly endless series of turns, bobbing up and down on one pointed foot and spinning around and around and around thirty-two times. How is this move - which is called a...

The Vector Properties of Angular Quantities
In this video Paul Andersen explains how a rotating system will have several quantities; including torque, angular velocity, angular acceleration and angular momentum. Each of these quantities have a vector property that can be...

Angular Momentum of a System
In this video Paul Andersen explains how the angular momentum of a system can be calculated by determining the angular momentum of all individual objects within the system. An inquiry activity using a gyroscope is also included.

Angular Momentum
In this video Paul Andersen explains rotating object have angular momentum. The angular momentum of a point object is the product of the distant from the center of rotation and the linear momentum. The angular momentum of an extended...

Rotational Motion
In this video Paul Andersen explains how a net torque acting on an object will create rotational motion. This motion can be described by the angular displacement, angular velocity, and angular acceleration. The linear velocity can be...

Angular Impulse
In this video Paul Andersen explains how the change in angular momentum is equal to the torque applied over a given time. A sample problem and inquiry activity are included.
