is it possible to make a frictionless surface on which a ball will roll without end?

Answer 1

There are a number of 4 dimensional shapes that would work. Good luck making them though.

Answer 2

Frictionless Surface

Answer 3

Oh I get what you're saying, like when you throw a ball down the bowling lane and it spins without affecting the motion direction of the ball much. So you are picturing a ball spinning in place indefinitely. Well I have two solutions that may be possible. One I'm certain of.

Number one is, assuming the ball is as perfect a sphere as you can get, you freeze water around it so the ball is now inside of a frictionless sphere. You would probably have to set the ball in motion inside the ice sphere BEFORE putting it into a vacuum(not sure how to do this, perhaps you could just move the ice around it and say that in a vacuum the motion of the ball is relative to the ice, therefore the ball is spinning hah). Assuming you get it into a vacuum while still spinning inside, I imagine it will continue to spin until removed from the vacuum and gravity interferes.

The second I am certain works, but doesn't not use a surface at all so I guess it doesn't meet your criteria, but anyway we're all living on it hehe.

Answer 4

Aside from the impossible ideals of frictionlessness and endlessness, a ball won't roll without friction. There has to be enough friction to apply some torque to the ball, otherwise it will simply skid along the surface like everything else.

Answer 5

It is impossible to make anything frictionless on earth. You can make things frictionless in a vacuum or in space. The best you can do is make something near little or no friction. Even if you make the surface frictionless there is still air friction involved too which is why you need a vacuum.

Answer 6

first how long the surface you will make? any how the surface has to end at 2km or 10km. (theoretically yes.) ice sheet intundra or in Antarctica behaves almost like a frictionless surface.
