This entertaining mini-lesson engages the learner in physical activity to explore the effects of a twisting force (torque) on rotational motion. By mimicking the motion of a skateboarder, learners gain an intuitive...

This website, from Physclips, provides a general explanation of the Foucault pendulum, which is a laboratory demonstration of the earth's rotation. Some historical material is presented, along with a discussion of the...

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 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...
