This video demonstrates the operation of a boomerang. A boomerang is shaped such that air passing over it will cause it to lift and turn. If thrown correctly, it will return to the thrower. The video is part of a...

This video demonstrates conservation of angular momentum. When a person on a rotatable platform (initially at rest) tilts the axis of a rotating bicycle wheel, conservation of angular momentum results in spinning of the...

This video demonstrates the conservation of angular momentum. In the experiment, as weights are pulled closer to the axis of rotation, a person on a rotating platform will spin faster due to a change in the moment of...
