1. The problem statement, all variables and given/known data What is the net force done on a driven pendulum? 2. Relevant equations Fd=mk (driving force) Fg=mg (Gravitational force) Fr=????? (Do I need to include this????) 3. The attempt at a solution Fnet = Fd + Fg = mk + mg I'm not sure if I need to include the restoring force, which was not given in the problem but I know it is there.
