Consider the two phase diagrams below in which velocity vs position is plotted for a spring-mass system. In both cases, a force (F) is present, in addition to the spring force. The equation of motion has the form
m = -kx + F
For each case, the green square indicates the start of the motion.
For each case, state whether the force is a dissipative or a driving force.
Consider the motion indicated by diagram B. Make a reasonable guess at the mathematical form for the time dependence of the total energy.
