| Abstract: | The moment of inertia of a system will decrese and the angular velocity will increse if the fluid in the system is lost continuously during its rotation. This can be used to demonstrate the principle of angular momentum conservation. |
| |
| Keywords: | angular momentum moment of inertia |
