UNIT: |
Angular Momentum |
|
PURPOSE: |
To demonstrate the physics of angular momentum using
a funnel and ball |
|
EQUIPMENT: |
| 1. |
Stand with clamp |
| 2. |
Glass funnel |
| 3. |
Clamp with ring |
| 4. |
Box with several small balls |
|
|
SUGGESTIONS: |
| 1. |
Let the ball roll down the funnel without circulating
around the funnel's axis of symmetry |
| 2. |
Start the ball rolling with a circulation as nearly
to the horizontal plane as possible |
|
|
|
|
DISCUSSION: |
For constant angular momentum, L=Iw with I=mr2,
w is proportional to the inverse square of the radius of rotation |
