In uniform circular motion, what is the correct relationship between the period and the frequency of rotation?

• A. The period is the time for one revolution and the frequency is the number of revolutions per second; they are related by $f=\frac{1}{T}$.
• B. The period is the number of revolutions per second and the frequency is the time for one revolution; they are related by $T=\frac{1}{f}$.
• C. The period and frequency are the same quantity measured in different units, so $f=T$.
• D. The period is the time for one revolution and the frequency is the angular speed; they are related by $f=\omega$.

Answer: (A)
