Angular momentum of a half filled waterbottle....

In summary, the conversation discusses the relationship between the angular momentum of a half-filled water bottle and whether it will increase, decrease, or remain the same. The question is posed in comparison to the angular momentum of the bottle at the moment it began spinning around its center axis. The conversation emphasizes the importance of providing all details in order to accurately answer a question.

when compared to the angular momentum of the bottle at instant when it started spinning.

Spinning around what axis?

about its center.

The center is not an axis. The axis is a line. It may go through the center. But there are many lines going through a point.
Look, you need all the details of a question before you can even think about an answer. You cannot expect people to read your mind and figure out by themselves what you want to ask.
 

FAQ: Angular momentum of a half filled waterbottle....

What is angular momentum?

Angular momentum is a measure of the rotational motion of an object, calculated by multiplying the moment of inertia by the angular velocity.

How is angular momentum related to a half filled waterbottle?

The angular momentum of a half filled waterbottle is determined by its shape, mass distribution, and rate of rotation.

Why is the water level important in calculating angular momentum?

The water level affects the moment of inertia, which is a key component in the calculation of angular momentum. A higher water level will result in a higher moment of inertia and therefore a higher angular momentum.

Can angular momentum change?

Yes, angular momentum can change if there is a change in the moment of inertia, mass distribution, or angular velocity of the object.

How is angular momentum conserved in a half filled waterbottle?

Angular momentum is conserved in a half filled waterbottle as long as there are no external torques acting on the bottle. This means that the moment of inertia and angular velocity will remain constant, resulting in a constant angular momentum.
