Question

You find out that it takes 2 seconds for the swing
to complete one cycle. What is the swing’s period and frequency

Answer 1

Period is a time quantity. Frequency is the cycles/second. Period is the seconds/cycle. As an example of the distinction and the relatedness of frequency and period, consider a woodpecker that drums upon a tree at a periodic rate. If the woodpecker drums upon a tree 2 times in one second, then the frequency is 2 Hz.
