Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

a. Consider a man running through the equator, with what velocity (direction and magnitude) should
he run so that he attain the minimum possible weight? Please explain understandably.
b. A wheel on an extremely low friction slanted surface will slide without rotating. However, if the
same surface is rough and having some friction the wheel will roll down (with rotation). Explain
why and how, using free body diagram.
