Does a vehicle turning on a banked road need to turn its wheels?
A vehicle drives in a circle on a track at constant speed at with radius of curvature $\rho$. The vehicle's acceleration is $$a = \upsilon' T + \kappa (\upsilon)^2 N \\ = \kappa (\upsilon)^2 N.$$
The ...

Does centripetal force remain the same if the radius increased and the mass decreased in that way the number of rotation remain as previous?
I copied this question from my textbook.
An object is being rotated in the vertical plane with a rope of length 90cm by a circus man. And the object rotates 100 times per minute. Suddenly the object's ...

How does friction allow bodies to rotate on merry go round? [duplicate]
I did check some answers on similiar questions here, but I wasn't satisfied with the answer.
When we are sitting (or if there is any body) on merry - go - round there should be some net force which ...

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 ...

How can the centripetal force lead to objects flying apart?
I don't understand how the centripetal force, which always points to the center of our circular motion can cause this scenario:
We have a big stone which spins very fast, so fast that a part breaks ...

Minimum velocity at the top of an object on a rope vs attached to a rigid body?
When working through a physics problem, I realized there's a fundamental difference between when an object is spinning in a circle and is attached to some rigid object such as a beam fixed to an axle ...

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 ...

Confusions about rotational dynamics and centripetal force
I am a high school student. I am having confusions about the centripetal force and rotational motion.
I have known that a body will be in rest or in uniform velocity if any force is not applied. But ...
