I have a formula which is G-force = velocity*omega/9.8. Omega is the angular velocity. I've seen on the internet that G force is actually acceleration/9.8. I'm confused as to which formula is correct. For simulating the motion of particle taking a turn, would omega simply be velocity divided by radius of turn? Assuming Cartesian coordinates.

Oh cool! Will ask there. Thanks :) – Nav Nov 23 '10 at 5:40

For circular motion, the two expressions are equivalent. Yes, in circular motion omega is velocity/radius. Acceleration in circular motion is velocity^2/radius.
