Does the centrifugal force of a rotating object acts at this same rotating object?
when rotating an object by a string a centripetal force from the string will act at the object towards the center and by Newton's 3rd law an opposite force will act at the string by the object . Then ...

What are centripetal forces for flywheel precession movement?
What are centripetal forces for this flywheel? I suppose for rotation around "inner" axis centripetal force is due to attractive forces between particles inside flywheel. However what about ...

Why is there no centripetal force acting on a vehicle while taking a turn in unbacked roads?
Can someone help me in understanding why there is no centripetal force acting on a vehicle while taking a turn?
Basically, my physics teacher used a non-inertial frame where the frame was at the ...

Basic concept of centripetal force - part 2
Let us imagine a body is moving in a circular path. There is a centripetal force working on that object. A common (mis)intuition would be since the body is rotating in a circle, the centripetal force ...

Basics of centripetal force
Suppose an object is moving in a circular path. We know that the net force that is working on that object is the centripetal force towards the center. But the object should have gone closer towards ...

EMI jee metallic rod rotating in uniform perpendicular magnetic field [closed]
A metallic rod is rotating about a vertical axis through its end. For finding the EMF $E$ between the ends we simply equate $m\omega^2r=Eq$ then find $\sqrt{-Edr}$. So for this calculation we consider ...

Torque of centripetal force
Suppose there is a particle of mass $m$ attached on the rim of an accelerating wheel. At any particular point, there should be a centripetal force passing through the IAOR, will this force apply ...

Why a rotating ball (at the end of a rope) does not fall down?
Is the explanation shown in the diagram right?
This is: the net force F1 = tangential + tension is way much bigger than the weight of the ball and, therefore, the resulting force F1 + weight is F1 so ...

What happens when you pull in on a rotating object? [duplicate]
I was wondering how rotating objects would behave if we pulled them inwards DURING rotation?
For example-
If I was initially spinning a rock attached to a string in a uniform circular motion
and then (...

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 ...

Why summing up the forces doesn't work? [closed]
I was trying to find out what the force on a rotating semicircular disc would be, and I know I can take the angular velocity and multiply it by (the distance between center of mass and the axis of ...

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 to computationally simulate a ball rolling down a curved track?
How can I accurately computationally simulate a bowling ball rolling down a bobsleigh track? (Initially ignore air friction and ice/concrete friction.)
I'm familiar with basic Newtonian mechanics, and ...
