Introduction
In this unit, we explore oscillatory motion, especially simple harmonic motion (SHM), and how systems like springs and pendulums store and exchange energy. Key ideas include amplitude, period, frequency, phase, damping, and resonance.
Summary of Key Equations
1. x = A·cos(ω·t + φ) (Position as a function of time)
2. v = –A·ω·sin(ω·t + φ) (Velocity in SHM)
3. a = –ω²·x (Acceleration in SHM)
4. T = 2·π/ω (Period of oscillation)
2. v = –A·ω·sin(ω·t + φ) (Velocity in SHM)
3. a = –ω²·x (Acceleration in SHM)
4. T = 2·π/ω (Period of oscillation)
