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 ...

Centripetal Force on a ball kept on a rotating disc
Suppose I keep a ball some distance $r$ away from the centre of a rotating disc. Let's assume I keep the ball gently and slowly so as to not impart any velocity to the ball.
If the disc were to be ...

Friction on a Spinning Platform
I do not understand at all why, if an object is sitting on a spinning platform, the friction force is towards the center. I understand the need for a centripetal force during circular motion, but ...

Why is there a centripetal force acting on the rear wheels of a car when cornering?
There are quite a few questions about this in the general case (i.e. what is the source of the centripetal force when cornering?) but I don't understand what the origin of this force is specifically ...

Centripetal Force Acting on a Belt and Pulley System [closed]
Just a warning: I am an A Level student looking for a simple but thorough explanation. I am happy to be introduced to new ideas, but a sesquipedalian answer with formulae that aren't derived will only ...

Friction and centripetal force [closed]
Let us imagine that some object (A car possibly) is moving in a circular path. At some point of time let's say that the driver of car made a turn in order to follow the circular motion. Now my ...

How is direction of static friction not opposite in direction but perpendicular when dealing with centripetal forces?
I was trying to wrap my head around this solution, and the whole idea of a car moving around a level curve, how the friction supplies the centripetal force. But I still can't wrap my head around the ...
