| http://www.w3.org/ns/prov#value | - F = D m d3x/dt3 + m d2x/dt2 + u dx/dt + k x (Equation 1) Here F represents the net external force acting on a body of mass m, D is a constant, as is the viscosity u (resistance to the movement of the body through a medium) and the restoring force constant k (such as in a spring or pendulum -- Hooke???s Law).
