Day 71: Simple Harmonic Motion Mathematical Analysis

Today we did the Simple Harmonic Motion Mathematic Computation lab from the Advanced Physics with Vernier: Mechanics lab manual. Students use a motion sensor to create a position vs. time graph, apply a sinusoidal curve fit, and then determine the relationship between the four coefficients of the equation and how to physically change the oscillator to affect those coefficients. It works really well and helps students better understand amplitude, offset, frequency, and phase. While motion detector baskets are sold from science suppliers, I found it cheaper to buy wire mesh bins for the local office supply company.
