give an expample of how an object in periodic motion can have a high SPEED but LOW frequency:
the periodic motion of the moon in orbit about the earth: the moon moves very fast (speed of about 100 m/s); its orbit is highly infrequent (makes a complete cycle about earth once every 27.3 days (a period of about 2.4 x 10^5 seconds) - that's infrequent).
