If there is no friction and the mass's displacement out of its equilibrium position at x = 0 is "small," the motion of a mass linked to a spring is simple harmonic motion.
Mode of antisymmetry Four. .Both this and the modes mentioned above might have variants.
Free motion is described by its normal modes at specific frequencies.The term "natural" or "resonant frequencies" refers to these fixed frequencies of the a system's normal modes.Natural oscillations of a mass on a spring occur at the a single frequency.
