Hello every one. but let me tell you a little about my self. My mine is always racing with new ideas it’s probably the A.D.D. I spend more time out of the box then in. I look at the world more in a quantum physic kind of way have a deep understanding on anything mechanical. Brilliant at problem solving making thing work with the tools and supplies I got on hand. I’m a hands on and very quick at catching on. My people skills are grate and open minded. I self taught myself basic electronics I have pretty much all the tools in that field you get the idea.

So how fast do I haft to go to get lift from a sphere?

I C. I think you could make a good argument that you would weigh more at the poles for exactly that reason. The reason is that at the pole our tangental velocity is equal to 0. The sum of the Forces has to still be equal to zero so since there is no tangental velocity and no centrifugal force component. It has to be true and here is why. Why do objects orbit the earth? It is because they are moving at such tangental velocity that the centrifugal force is sufficient to overcome gravity just enough that the object misses the earth on its re-entry trajectory. I would imagine that if you were going fast enough (and omitted things like friction from air and such as they would make you incinerate) you could accelerate yourself fast enough so that you could orbit the planet only inches above the earth's surface.

If the world is round with gravity and the centrifugal force y don’t we weight more at the poles?
