ball physics

how can i set up a physics for a ball so it moves smoothly and with gravity?
Currently I have it set up with an accelerate behavior that accelerates it down. the problem is when an actor rotates from under it the ball wont fall/roll until its completely upside down .

most of us use that for gravity
