Differential Equations Resources


For a problem where you have a vertical damped spring with an applied force, you have a variety of forces. The basic force equation from Newton's second law is, of course, F=ma or, if we want to put everything in terms of position u, Fnet=mu'', where u'' is the second derivative of position with respect to time (some books use x or y for position instead). This net force is equivalent to a... read more
