Help w/ jittery circles using physics

So I'm trying to have a ball move around a circle. It's not smooth at all and I'm not sure what I'm doing wrong.

Here's a capx file:

Hi,

you cant use the physics behavior with the platform behavior in this way. Physics objects should be controlled with physics forces otherwise you get odd results.

Thanks spongehammer!
