All the periodic motions are repetitive but all the repetitive motions are not periodic . Explain .?
This question is from physics .
Answer:
Periodic ( aka simple harmonic) motion is repetitive because it is the same motion at the same speed over and over again. Think of a pendulum swinging back and forth. It follows the same path and takes the same amount of time to complete its cycle.
Repetitive motion is not held to the same restrictions as periodic (simple harmonic) motion. Repetitive motion means to do the same thing over and over again, but it does not require the same time frame. People get carpel tunnel syndrome from repetitive motion at the computer, but they do not always type the exact same word over and over again in the same amount of time. A school bus driver takes the same route to and from school each day picking up and dropping off kids. Sometimes she skips a stop because the child is not there. Her time for each trip may be about the same, but her trips are never identical.
