Torque and angular momentum

This course is a part of Physics, a 20-course Topic series from Khan Academy.

Everything you've learned about motion, forces, energy, and momentum can be reused to analyze rotating objects. There are some differences, though. Here, you'll learn about rotational motion, moments, torque, and angular momentum.

This course contains 2 segments:

Rotational kinematics

Learn what angular displacement, angular velocity, and angular acceleration mean, as well as the relationship between them.

Torque, moments, and angular momentum

Until this tutorial, we have been completely ignoring that things rotate. In this tutorial, we'll explore why they rotate and how they do it. It will leave your head spinning (no, it won't, but seemed like a fun thing to say given the subject matter).
