$A$ particle is moving in a circle of radius $5 \,cm$ with uniform speed and completes the circle in $5 \,s$. What is the magnitude of linear acceleration?

Two particles $A$ and $B$ are moving in uniform circular motion in concentric circles of radii $r_{A}$ and $r_{B}$ with speeds $v_A$ and $v_B$ respectively. The time period of rotation is the same. The ratio of angular speed of $A$ to that of $B$ will be

The position vector of a particle is $\vec{r} = (a \cos \omega t)\hat{i} + (a \sin \omega t)\hat{j}$. The velocity of the particle is

What is the angular velocity of the second hand of a clock?

Angular speed of the hour hand of a clock in degrees per second is:

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