F = m*v^2/r

F = the centripetal force (i don't know if this is a correct word )

m = mass

v = velocity

r = distance

If that didn't quite clarify it enough:Originally posted by HallsofIvy

When you swing the bucket in a circle, there is a force pulling toward the center of rotation, which would probably be at your shoulder. When the bucket is above your head, that force is pulling downward. If you are swinging fastly enough, the force generates acceleration that is greater thant the acceleration due to gravity. So the water cannot escape from the bucket due to gravity, because the bucket is accelerating downward faster than gravity is causing the water to. It's like trying to run away from an olypmic runner. Basically, as long as the water and bucket are putting a substantial amount of pressure on each other, the water won't fall out of the bucket.

In the bucket you are swinging around you put a piece of wood,

if the bucket is above your head, will the wood be at the same level

in the water as it was in rest ?

this question was asked during a science quiz here in Holland.

Really nobody knew the answer, nor had any idea, maybe one of you?

Due to the velocity that it has, at every point in its motion, it deviates from the path of falling, and due to the force of gravity, from following a tangential path.

And what keeps the bucket from flying off is your hold on it.

5.98 X 10^24 kg. I know that I am supposed to use the formula T=2 Pi (r^3/2) / square root of GMe, and then when I get my answer for that I divide by 86400 to express my answer in days. I think my answer should be somewhere around 27.153 days, but I am not getting anything close to that. I have worked and worked the problem out and I just cannot solve it. I think I may be using my calculator incorrectly. I am coming up with an answer of 2.68^11 and then when I divide that by 86400 I get 3101851.852, which is very wrong. Please help!
