Question
1)Suppose you are standing on the edge of a spinning merry-go-round. You step off, at right angles to the edge. What effect (if any) does this have on the angular speed of the merry-go-round? Be sure to consider what circumstances can cause a change in angular momentum. Explain your answer
2) Now consider the above question the other way. You are standing on the ground next to a fast-spinning merry-go-round and you step onto it. Does this have an effect on the rotational speed of the merry-go-round? a. It will make the merry-go-round speed up. b. It will make the merry-go-round slow down. c. It will have no effect on the rotational speed of the merry-go-round.
Explanation / Answer
a) Angular momentum = I w is constant unless External torque is applied
If a person steps down I decreases, which imples angular velocity w increases
b) If a persons steps on I increases, which imples angular velocity w decreases
