Watch the following video tutorial on cyclic (periodic) motion, then take the quiz.
Cyclic Motion Video

Summary:

• Motion that has a repeating pattern is called cyclic motion (or periodic motion).

• The time it takes to complete one full cycle, such as one rotation, is called the period.

• Frequency is the number of cycles per second.

• The amplitude indicates the size of the motion, for example, the stride length in a walk cycle.

• For rotation, the amplitude is the circumference, which depends on the radius of rotation.

• The speed of the motion increases with both amplitude and frequency.
