Define periodic motion in your own words.
Think about rhythms in nature or mechanical systems.
What is the SI unit of frequency?
Recall how we measure oscillations.
What is the time needed for one complete cycle of periodic motion called?
Remember how oscillations are measured.
True or False: The frequency of a wave is inversely proportional to its period.
Consider how often the wave oscillates.
A 0.5 kg mass attached to a spring moves in simple harmonic motion with a spring constant of 200 N/m. What is the period of oscillation?
Use the formula for the period of a mass-spring system.
If a pendulum's length is doubled, how does its period change? Show your work.
Consider how the formula alters when L is modified.
