What is the centripetal acceleration of an object moving at constant speed $v$ in a circle of radius $r$?

정답

$a_c = \frac{v^2}{r} = \omega^2 r$, directed radially inward toward the center of rotation.

해설

Centripetal acceleration alters the direction of velocity without changing speed. Centripetal force required is $F_c = m a_c = \frac{m v^2}{r}$.
