Mechanics
- 01VectorsScalars vs vectors, resultants, and components in 1D and 2D.
- 02Motion in one dimensionPosition, distance vs displacement, speed vs velocity, acceleration from graphs.
- 03Equations of motionThe four equations for constant acceleration in a straight line.
- 04Mechanical energyE_k = ½mv², E_p = mgh, and conservation when non-conservative work is zero.
Waves
- 05Transverse pulses & wavesPulse vs wave, amplitude, wavelength, frequency, period, speed v = fλ.
- 10Electromagnetic radiationEM spectrum from radio to gamma, c = fλ in vacuum, and energy of a photon E = hf.
- 11SoundSound is a longitudinal mechanical wave. Pitch is frequency, loudness is amplitude, quality is waveform. Needs a medium.
- 12Pulses & superpositionA pulse is a single disturbance. Superposition: amplitudes add. Constructive vs destructive. Pulse speed depends on the medium.
