What happens to the motion of a mass-spring system in the presence of friction? Theory lab: what is the function \(x(t)\) if there is a frictional force, proportional to velocity, \(-bv\), exerted on the spring mass system? Propose an experiment to test whether the period of the motion of pendulum depends on the amplitude of the motion.
