In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...

Speedy Spinning Spheres! Using spheres, cylinders, and straws, the Crew and Dr. Rob learn about inertia, velocity, and conservation of energy due to angular momentum. STEM Challenge: Angular Momentum ...

It's almost always the last topic in the first semester of introductory physics—angular momentum. Best for last, or something? I've used this concept to describe everything from fidget spinners to ...

A student in your dynamics class has decided to become a stunt bike rider. One of the first stunts undertaken is a long jump on a motorcycle. The student’s inspiration for this was the setting of a ...

This concept robot uses angular momentum to roll around. You can see that on either end of the robot there are two discs which have been cut on one side to make them off-balance. For locomotion, two ...

Click to open image viewer. This artifact is a momentum wheel--a device used on a satellite to maintain stable attitude (its position relative to the Earth). A satellite in orbit has a total angular ...
