I am modeling some king of walking system, and I need to use air spring. The one that is conventionally used (I think so) has an energy equation like:

U(x) = K/2 * (1/x^2 - 1/x0^2)

I am trying do derive the "force" equation for this air spring so I can use if with Newton's second law equations of motion.

Would you please help me with this. Thanks.
