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 ...

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 ...

If you're holding on to a playground spinning wheel and then let go, is your trajectory straight or curved?
Let's say you are on one of those playground spinning wheels and then you let go. I've heard that you will fly off tangentially to the wheel, but do you really fly off in a straight line, since you ...

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 ...

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 ...

Normal force in a hypothetical rotating space station with artificial gravity
In order to simulate gravity on hypothetical space stations, one approach involves rotating the space station so that a centripetal force is present. Occupants within the space station's frame of ...

Why does a ball tied to a spring move outwards when rotated (ground frame)?
Suppose a bob or a ball is tied to a spring which in turn is pivoted to a certain point on a table as shown, if the ball is given velocity $v_o$ perpendicular to spring it moves in circular motion and ...

How many components does the net force have on a rotating object?
I understand that there is the radial and tangential force components acting on a spinning object, but according to the attached image from my book, there is a third component F_1z that is ...

How do you calculate the distance from center for centripetal force equation for long objects such as board or a hammer?
I am trying to calculate the centripetal force for an enlongated object like a fan blade. Where do I measure to to get the distance from center. Would I measure from the center to the end of the ...

Centripetal Force Formula Confusion
After I finished studying and trying to test my knowledge to see what I have learned, I realized I am confused about the centripetal force formula:
$$F_c= \frac{mv²}{R}$$
which I know is also equal to ...

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 ...

What forces are responsible for the circular motion of the center of mass of a gyroscope-like setup in precession?
Suppose we have a disk (of mass $M$) connected to a rod (of mass $m$) attached to a fixed pivot. (Note that initially I thought of the rod hanging off a rope, but I realized it would be better to ...

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 ...
