My question here is: Does it matter? Since position is a linear function of velocity (which is changing, but we've got that handled with the RK4 for velocity), do we need RK4 for both, or does it suffice to have RK4 for simply velocity, so I can make 4 approximations for the acceleration term. mariano garcia attorney
