Summary:

• Vibrational motion is another example of cyclic (or periodic) motion.
• Elastic materials vibrate with a frequency that depends on the stiffness and the mass.
• The frequency of elastic vibrations does not depend on the amplitude of the motion.
• The spacings for elastic vibrations are closely related to those of uniform circular motion.
• As with swinging motion, the texture in the timing is most noticeable near the extremes.
