1. Section 19.2 Graphs of Harmonic Motion

2. Review Frequency and period are inversely related. The period is the time per cycle. (cycle-unit of repeating motion) The frequency are the number of cycles per time. (Hz) Based on your lab, which variable, (length, mass or amplitude) changed the period the most? T = 2 π √L/g

4. Linear Motion vs. Harmonic Motion Graphs

6. Phase Tells us exactly where an oscillator is in its cycle-measured relative to the whole cycle. Phase is measure in degrees Most important in comparing two oscillators Out of Phase- 90 or 180 degrees
