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 ...

What torques or acceleration is required to move a differential drive robot on a circular path?
When a differential drive robot moves on a circular arc with constant speed, its kinematics gets me constant wheel velocities. This appears to suggest that once a circular motion is reached and ...

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 ...

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 ...

How does the centripetal force on the butt of a golf club's shaft produce torque that rotates the club/clubhead forward?
In the top picture, which is how torque is typically explained, the center of rotation is different than in the bottom picture. I think I understand how this works in the top picture, but I don't see ...

Force applied on edge of a cylinder due to water
We take a horizontal cylinder of length $L$ and fill it with incompressible water of mass $m$ and close the two ends with lids. If we start rotating the cylinder with respect to one of the ends,the ...

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 ...

Explaining rotation without mathematics
I understand why an object rotates about its centre of mass from a mathematical perspective but I have been trying to think how we can explain this in terms of the bonds within the object. Feel free ...

Ball in a spinning disc
So imagine we have a disc at rest and a ball at the middle of its radius. Now the disc starts rotating with constant angular velocity. Where will the ball go? Will it remain at $R/2$?
Watch this ...

Help determinating the force equation for this circular motion problem
Let's talk about the object B.(using cordinate system but unit vector θ is 0 so I'll ignore that).
So on one side I think the force equation for B is :
Because I think when the radius is also ...

Circular motion of car on circular track with help of friction - its translational component and rotational component?
Correct me if I am wrong -
(a) While doing circular motion car is doing pure rotational motion as it rotates around a fixed axis [i am talking about motion of real car which turns its position]
(b) ...
