$A$ scooter is going round a circular road of radius $100 \,m$ at a speed of $10 \,m/s$. The angular speed of the scooter will be ......... $rad/s$.

$A$ motorcyclist going round in a circular track at a constant speed has:

$A$ body moving in a circular path with a constant speed has constant:

$A$ particle is moving along a circular path with constant speed and centripetal acceleration '$a$'. If the speed is doubled,the ratio of its acceleration after and before the change is:

If the direction of motion of an object performing uniform circular motion is reversed,what will be the effect on the direction of the centripetal force?

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
