Can someone explain this demonstration to me its the one where someone stands on a disc but it won't spin until the wheel does. Specifically I want to understand the conservation of angular momentum where the wheel flips over.

near the bottom.
Thanks for any help.

The mathematical reason is that angular momentum is a vector that is it has a direction as well as a magnitude. This isn't much help unless you have studied vectors.
An analogy is if you were standing on the disk and through a ball you and the disk would move in the opposite direction to conserve linear momentum. When you rotate the wheel the direction of angular momentum of the wheel changes so you and the disk will turn to compensate or conserve the directional components of angular momentum.

artwork out the circumference of the bike wheel, that's 27*pi. Circumference equals eighty 4.eighty two inches. Convert miles to inches, or vice-versa, then divide distance by way of circumference. i will permit you are attempting this on the grounds that i purely be conscious of metric values.
