Circles and Acceleration

  • #1
If I take a perfectly rigid disk 10 miles in diameter and set it spinning at a constant speed. Is the constant acceleration an object experiences riding 5 feet from the center the same as it would be if it were 5 miles from the center? I know many other things would be different but I mean the acceleration alone.

Thanks

No, this follows directly from the centripetal acceleration equation (as well as intuition).

No

a = -(2Pi/T)^2 *r (Wish I could learn Latex..)


The acceleration is directly proportional to the distance from the centre of rotation.

Ahhh.... momentary insanity. Isn't it great? :rolleyes:
