No work needed! A) In order for simple harmonic motion (vibration) to occur: Group of answer choices A randomly varying force must be applied to the system A constant force must be applied to the system A force that attempts to push the system away from an equilibrium position must be applied to the system A force that attempts to restore the system to an equilibrium position must be applied to the system B) In a simple harmonic system, damping...
