Problem

A log–log plot of rotational kinetic energy

K_{\text{rot}}

versus angular speed

\omega

for a rigid object yields a straight line with a slope of

2.0

. Explain what this slope indicates about how

K_{\text{rot}}

depends on

\omega

, and state the physical significance of the line’s vertical intercept.
