Does an object performing a uniform circular motion rotate even when there is no angular acceleration?
Is a tangential acceleration, and thus an angular acceleration necessary for rotation to occur? If an object in a UCM rotates then would centripetal acceleration be sufficient to induce rotation? Then,...

Why does the bottommost point of a rolling body have a radial acceleration in the ground frame?
Let's say a solid cylinder of radius r is rolling on a stationary horizontal surface with linear velocity v, angular velocity $\omega$, linear acceleration a and angular acceleration $\alpha$
Bottom ...

How the centripetal forces work on a point in a rigid body? [closed]
I know it was a question but when I asked last time I did not know the answer. It has been suggested that the question is not clear, it's badly written. Now I know the answer and I can introduce them ...

Is the acceleration of a rotating body always it's centripetal component? [closed]
For constant circular motion where a rotating mass accelerates angularly.
Would the linear acceleration of the rotating mass always be equal to its centripetal acceleration
e.g. The earth's ...

Tension in a rod rotating about a fixed point
A rod of mass $m$ and length $l$ is rising about a fixed point in the ceiling with an angular velocity $\omega$ as shown in the figure.
Now, on taking a small element on the rod, the net tension ...

Is rotational motion conditioned to a central force?
We know rotational motion as a combination (a resultant) of two effects the tangential velocity and a centripetal force. Does rotational motion turn into linear motion at the same instance this ...
