Would an unwrapping tetherball be able to steal all earth momentum?

In summary, the conversation discusses the concept of tetherball and its relation to gravity and angular momentum. It is agreed that the tetherball does not break the conservation of angular momentum, as its motion is perpendicular to its acceleration towards the center pole. The idea of stealing Earth's angular momentum is mentioned, but it is stated that further discussion will only continue if the individual shows a willingness to learn physics. There is a mention of a previous forum discussion on the topic and a suspicion that the individual may be using a different name.

neglecting gravity in this problem the tetherball starts in the pole with a pole XD thickness of 1m

if the tether spins oposite to Earth the Earth pulls on the string a revolution every 24 hours accelerating the tetherball opposite sense

doesnt this agree with conservation of angular momentum?

i don't make any affirmation I am just asking

The tetherball is accelerated toward the center pole, in a direction exactly perpendicular to its motion. Hence, it does not increase its speed linearly or increase its angular momentum. It doesn't affect the Earth's angular momentum at all.

Do a forum search for "tetherball". And please tell us that you are not eosphorous under a different name (but only if it's true, of course).

my point is that a tetherball APARENTLY breaks the conservation of angular momentum because it keeps a constant linear speed however the radius

after pages of discussion here its been agreed that the tether gets that extra angular momentum from earth

from there my idea to steal ertahs angular momentum

There is no such thing as "apparently" - it either does or it doesn't (hint: it doesn't).

Have you even tried to apply some math to calculate what happens here? We're not going to indulge your rambling rants. You need to show that you are willing to actually learn physics if you want these discussions to continue.

Dang! You beat me to the 'Aviator Alert'.
 

FAQ: Would an unwrapping tetherball be able to steal all earth momentum?

1. Can an unwrapping tetherball really steal all earth momentum?

The short answer is no. While it may seem like a fun thought experiment, the laws of physics make it impossible for an unwrapping tetherball to steal all of Earth's momentum. There are various factors such as the tetherball's size, mass, and speed that would affect its ability to even slightly impact Earth's momentum.

2. How much momentum could an unwrapping tetherball realistically steal?

It is difficult to accurately determine the amount of momentum that an unwrapping tetherball could steal, as it would depend on many variables such as its size, speed, and the surface it is bouncing on. However, it is safe to say that the impact would be negligible and would not significantly affect Earth's momentum.

3. What would happen if an unwrapping tetherball somehow managed to steal all of Earth's momentum?

In a hypothetical scenario where an unwrapping tetherball could steal all of Earth's momentum, chaos would ensue. The Earth's rotation and orbit around the sun would be drastically affected, leading to catastrophic consequences for all life on the planet.

4. Is there any scientific evidence to support the idea of an unwrapping tetherball stealing Earth's momentum?

No, there is no scientific evidence to support this idea. It is purely a thought experiment that goes against the laws of physics and the principles of conservation of momentum.

5. Can a tetherball steal momentum at all?

Yes, a tetherball can steal momentum, but only a small amount. When the tetherball is hit, it exerts a force on the pole, causing it to move slightly in the opposite direction. However, this amount of momentum is insignificant and would not affect Earth's momentum in any noticeable way.
