Which is true: objects keep spinning because of inertia, or objects keep spinning because of centripetal force?
I'm hoping any gravity or friction can be ignored.
I gather a spinning object is a non-inertial frame. I suppose that's because change of direction is acceleration. Continued acceleration requires ...

Is visualising centripetal acceleration, as pulling the rotating body towards the centre, correct?
Centripetal force would literally mean ‘the centre-seeking force’. So in order to bring a body towards the centre it turns it and the body is always trying to reach the centre however is unable to ...

How to find centripetal acceleration of a 2D object like disc
I am able to find centripetal acceleration of point object but a question came in my test which asked us to find:
The centripetal acceleration of a disc (a 2D object), revolving around its center ...

Einstein's equivalence principle and acceleration due to rotation
Einstein's equivalence principle is often illustrated by pointing out that a person trapped in an elevator has no way of telling whether they are on the surface of the earth or in deep space in a ...

Is centripetal acceleration independent of linear acceleration in accelerated circular motion?
Can we say that there is a relationship between them, or are they independent of each other? why?
Like does $a_c=v^2/r$ imply $a_c$ and $a_{tangential}$ are related?
I am very confused by this ...

Centripetal acceleration of Centre of mass of rolling body
Does the centre of mass of body rolling on a stationary floor experience centripetal acceleration downwards towards the IAOR (instantaneous axis of rotation) which here is the point of contact of body ...

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 ...

Normal Force in Circular Motion
In the above diagram, sec 1 (on the left side), an object of mass $m$, after releasing from rest from a slant track, continues into a vertical circular track. At a random position on the circular ...
