I appreciate any help! 8 kids on a "merry go round" are the the outer edge and move to the center. If the original angular velocity was 2 rad/sec and the moment of inertia went from 50 kg * m^2 to 40 kg * m^2, what is the new angular velocity? Thanks for helping out!

I think angular velocity will not change
shamim
  • shamim
Angular velocity depends on angular displacement nd time
shamim
  • shamim
Angular displacement of a man outerside of a circle= angular displacement of a man innerside of a circle

but wouldn't it change with a new moment of inertia @shamim ?
shamim
  • shamim
No
shamim
  • shamim
U know moment of inertia=m*r^2
shamim
  • shamim
So moment of inertia will b higher with higher radius of a circle
shamim
  • shamim
Nd moment of inertia will b dicrease with lower value of radius of a circle r

but wouldn't that mean the displacement got larger, changing the angular velocity
shamim
  • shamim
Displacement is 2 kinds
shamim
  • shamim
1 is linear displacement nd angular displacement
anonymous
  • anonymous
oh, I see. The change is linear, but not angular
shamim
  • shamim
U know angular velocity=angular displacement/time

I see, thank you very much!
