This web page, authored and curated by David P. Stern, introduces vectors as an extension of numbers having both magnitude and direction. The initial motivation is to describe velocity but the material includes a general...

The Physics Classroom presents this tutorial on the theory and fundamentals of vectors. Throughout the tutorial, students will learn how to “explain and analyze the motion of objects in two dimensions.” Some of the key...

Authored by Professor G. Eric Matthews, this web page describes a project at Wake Forest University to create videos of common physics lecture demonstrations. The goals of the project, the participants, some details...

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...
