The angular speed of Earth around its own axis is ......... $rad/s$.

$A$ particle moves in the $x-y$ plane according to the rules $x = a \sin \omega t$ and $y = a \cos \omega t$. The particle follows:

If $\vec{L}$ and $\vec{P}$ represent the angular momentum and linear momentum respectively of a particle of mass $m$ having position vector $\vec{r} = a(\hat{i} \cos \omega t + \hat{j} \sin \omega t)$,the direction of the force acting on the particle is:

$A$ body performing uniform circular motion of radius $R$ has frequency $n$. Its centripetal acceleration is

In the case of uniform circular motion,which of the following physical quantities does not remain constant?

In uniform circular motion,the velocity vector and acceleration vector are
