Answer;

Periodic motion                                           Non-periodic motion

A motion repeating itself at -               A motion that repeats itself is                 m                                                           considered a non-periodic motion but

                                                        |        not at regular periods of time.

  -   regular intervals is

regarded as periodic motion
