Angular momentum is constant when there is no net torque. View this Khan Academy video addressing the conservation of angular momentum. [10:12]

This is the glossary of terms and definitions used in Chapter 10: Rotational Motion and Angular Momentum from the AP Physics online text.

This page provides a summary of each section in Chapter 10: Rotational Motion and Angular Momentum from the AP Physics online text.

Video [7:28] in which Paul Andersen explains in a clear and understandable way, that rotating objects have angular momentum.

A few examples of what the conservation of angular momentum is and understand how it works. Challenge comprehension with follow up questions for discussion and problems for solutions.

Watch as Ryan spins a bike wheel where nothing crazy happens. But something weird happens when he flips it over. Learn about the conservation of angular momentum in this demonstration. [2:15]

A very technical explanation of the angular momentum of an electron.

Predict changes in gravitational potential energy and angular momentum for a system of two masses.

By the end of this section, you will be able to describe the right-hand rule to find the direction of angular velocity, momentum, and torque; explain the gyroscopic effect; and study how Earth acts like a gigantic gyroscope.

After reading about the historical development of concepts of conserved motion, students are directed to a series of activities to gain a better understanding of momentum, conservation of momenta, angular momentum, and conservation of...

Learn that a torque is applied when a force causes an object to rotate around an axis in this video. Video overviews net torque and how to determine if torque is positive or negative. [9:24]

Solve problems by using the Law of Moments in this video. Understand that moments is essentially the same concept as torque as explained in this video. [14:13]

Solve problems by using the Law of Moments in this video. Understand that moments is essentially the same concept as torque as explained in this video. [13:49]

This video explains that there is a concentrated point in an object where all the mass is held called the center of mass. It also explains that if an object is supported at the center of mass there is no net torque on the object. Learn...

Learn how to find the direction component of torque with this video. Review vector quantities to understand how to apply the right hand rule to a torque problem. [10:00]

[Free Registration/Login may be required to access all resource tools.] In this online lesson students will begin to understand what is meant by a rigid body. Learn what torque is and how to use it in solving problems.

Learn about the concept of torque and angular concept in this review video. [19:03]

This site is from the Physics Department at Georgia State University. The conservation of energy as a fundamental conservation law is presented and compared to other conservation laws (momentum and angular momentum). Links to further...

Students learn the concept of angular momentum and its correlation to mass, velocity and radius. They experiment with rotation and an object's mass distribution. In an associated literacy activity, students use basic methods of...

Ever notice how flying acrobats, gymnasts, ice-skaters and half-pipe snowboarders, tuck in their arms and scrunch up their bodies while spinning in the air? By keeping their arms and legs tucked close to their centers of mass, they are...
