    Spin
In summary, the conservation of angular momentum is the primary reason for an object to continue spinning without stopping. An object's shape can affect its spin, with more symmetrical shapes spinning more smoothly. Friction can slow down an object's spin by creating an external torque. In theory, an object's spin can be stopped completely with an equal and opposite external torque. However, in practice, it can be difficult to completely stop an object's spin due to factors such as air resistance. There is also a limit to how fast an object can spin, known as the critical speed, beyond which the object would start to break apart.

i tried the following test, and found it wouldn't stop spin and in fact would spin more faster if u low it 2 or 3 mm and raise it up 2 or 3 mm during it spins.

the "illustrated diagram" (the best i could draw using paint shop pro) :p

FAQ: I found this wouldn't stop spin

What causes an object to continue spinning?

The conservation of angular momentum is the primary reason why an object would continue to spin without stopping. This law states that the total angular momentum of a closed system remains constant unless acted upon by an external torque.

Can an object's shape affect its spin?

Yes, an object's shape can affect its spin. Objects with a more symmetrical shape will spin more smoothly and evenly, while irregularly shaped objects may have a more erratic spin due to uneven distribution of mass.

How does friction play a role in an object's spin?

Friction can slow down an object's spin by creating an external torque. As the object spins, the friction between its surface and the surface it is spinning on creates a force that acts against the direction of the spin, eventually causing it to come to a stop.

Can an object's spin be stopped completely?

In theory, yes, an object's spin can be stopped completely. This would require an equal and opposite external torque to counteract the object's angular momentum. However, in practice, it can be very difficult or even impossible to completely stop an object's spin due to factors such as air resistance and imperfections in the surface it is spinning on.

Is there a limit to how fast an object can spin?

Yes, there is a limit to how fast an object can spin. This is known as the critical speed or the speed at which an object's centrifugal force equals its gravitational force. Beyond this speed, the object would start to break apart due to the high rotational forces acting on it.
