Physics 201 Homework
... There are three forces here. The support force from the hands, the feet, and the person’s weight. We need to choose an axis of rotation. Any axis will work because the system is at rest, in equilibrium. There are three natural places to consider: each place where there is a force. Whichever point we ...

lab #4: rolling friction - Physics
... For the upward moving points, make plots of x vs. t and y vs. t, and then make quartic polynomial fits to these. If the cubic or quartic terms are large compared to their uncertainties (as reported by WPTools), consider realigning your camera and/or launching the cart on a path more nearly parallel ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
