#### What is the relationship between force and kinetic energy

So Force = E / 1/2 v t = 2E / v t So Force is the twice rate of change of Energy with respect to the velocity x time But as we know Albert said E= m c squared We put this into the equation Force = 2 m c squared /vt So if m and c are constant the force is the inverse of the velocity x time 1 / vt scaled up by the mass x the speed of light...
