Period & Frequency

Essential Questions

1. What's the connection between simple harmonic motion (SHM) and universal cirucular motion (UCM)

2. How are period, frequency, and time related?

H.P.3D.4 Use mathematical and computational thinking to analyze problems that relate the frequency, period, amplitude, wavelength, velocity, and energy of sound waves.
