SUMMARY

The discussion centers on the theoretical implications of a tetherball's motion in relation to Earth's angular momentum. Participants assert that the tetherball, when spun opposite to Earth, does not affect Earth's angular momentum, as it accelerates toward the pole without increasing its linear speed. The consensus is that the tetherball does not break the conservation of angular momentum, and any perceived increase in momentum is derived from Earth's own angular momentum. Participants emphasize the necessity of applying mathematical principles to fully understand the physics involved.

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
 
Physics news on Phys.org
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'.
