1. Problem My professor has given four problems, all of which I understand how to do, but he is asking us to "Write down the equation of motion for the system." The force is given or must be contrived in each problem. 2. Relevant equations We're using Newton's Second Law F=ma 3. The attempt at a solution So should I set the Force equation on the object equal to "m(dv/dt)" and integrate so that it's basically the integral of: Fgiven=ma Fgiven=m dv/dt Fgiven/m (dt) = dv which gives an equation for the velocity. So basically, is an equation for the velocity what the professor means by "equation of motion for the system"?
