For 10 points, name these objects displaying periodic motion, examples of which include a mass on a spring and a pendulum.
One quantity defined for these objects is given by 2pi times the peak energy stored over cyclical energy dissipated, also known as the quality factor. One example of these objects requires the small angle approximation that sine theta equals theta, and another requires a frictionless surface to avoid damping. These objects exhibit resonance when they are driven at the right angular frequency, which may be square root of L over g or square root of k over m for two examples of these objects.
