Oscillations and Waves - Simple Harmonic Motion

Question 1

simple harmonic motion

Answer 1

• oscillatory motion under a retarding force proportional to the amount of displacement from an equilibrium position
• 1. Amplitude A = how large the oscillation is = distance from the middle (EP) to the ends. Unit = m
• 2. Period T = how much time an oscillation takes = how many seconds per one oscillation.
     Unit = s
• T = seconds / oscillations
• 3. Frequency f = how many oscillations happen per second. Unit = Hz, “Hertz”, = osc/sec.
• f = oscillations / seconds
