If an object is spinning with 100 m radius and the radius becomes 0 what happens?

my educated guess is that with 0 radius the object would start rotating around the axe to keep the kinetic energy

this would mean a transformation of translation into rotation

am i correct?
:rofl:

First off you had to do a heck of a lot of work to reduce the radius.

not really if you crank the spinning with the pulling by gearing the axe with the radius bar

you apport a initial speed of 100 m/s to the object and according conservation of energy the object should keep those 100 m/s for ever (neglecting friction)

the bar radius would be geared with the axe transforming the spinning into pulling

i don't care how you gear it you have a lot of work to do.

Please take a break from your wild imagination and go find a physics book.
