$A$ motor shaft rotates at a constant angular velocity of $3000$ revolutions per minute. Through what angle (in radians) will it rotate in $1$ second?

The angular speed of a flywheel making $120 \, \text{revolutions/minute}$ is:

How much work is done by the centripetal force on an object moving in uniform circular motion?

If a body is moving in a circle of radius $r$ with a constant speed $v$,its angular velocity is:

Two objects of masses $m_1$ and $m_2$ are moving in circles of radii $r_1$ and $r_2$ respectively. Their respective angular speeds $\omega_1$ and $\omega_2$ are such that they both complete one revolution in the same time $t$. The ratio of the linear speed of $m_2$ to that of $m_1$ is:

$A$ particle is moving in uniform circular motion. About which point in the plane of the circle will the angular momentum of the particle always remain conserved?
