• Simple Harmonic Motion (SHM)The restoring force F = −kx, x = A sin(ωt + φ), velocity and acceleration, period, springs, pendulums and phase.
• Energy in Simple Harmonic MotionKE = ½k(A² − x²), PE = ½kx², the constant total ½kA², energy in time, energy methods, springs and pendulums.
• Wave MotionKinds of waves, λ, f and v = fλ, y = A sin(kx − ωt), wave speed in different media, intensity and reflection.
• Superposition of WavesWaves add: interference, standing waves, harmonics of strings and organ pipes, and beats.
• Doppler EffectMoving sources and listeners, the general formula and its signs, echoes and radar, light, angles and shock waves.
