Question

A volunteer is holding a rapidly rotating horizontal bicycle wheel with two handles as shown in the image attached! The volunteer rotates the bicycle wheel so that the upper hand holding it becomes the lower hand. What effect does this have?

***Answer choices and image attached inside! not sure :/ thank you very much! :)

Answer 1

A. The angular momentum of the wheel changes in direction and magnitude.

B. The angular momentum of the wheel changes in direction, but its magnitude is about the same.

C. The angular momentum of the wheel changes in magnitude, but its direction is about the same.

D. The angular momentum of the wheel is unchanged in both magnitude and direction.

:/

Answer 2

picture!

Answer 3

what defines momentum?

Answer 4

mass in motion?

Answer 5

is it a vector ?

Answer 6

ohhh oops haha

yeah it's a vector i think

is that right?

Answer 7

i believe its a vector, and a change in position would change direction right?

Answer 8

yes:) ohh okay, so now it's narrowed down to choices A and B then? since direction would change?

im not sure about magnitude though :/

Answer 9

the forces from the rotating wheel shouldnt change too much so magnitude is relatively unaffected in my view.

Answer 10

ahh okie! so it's choice B then? :O

Answer 11

if i were to take a stab at it, B would be my best guess yes

Answer 12

ooh okay! yay!! thanks so much!! :)

Answer 13
