Topics 5
- Periodic motion; time period and frequency; SHM as the projection of uniform circular motion on a diameter
- Displacement, amplitude, phase and epoch; differential equation d^2y/dt^2 + omega^2 y = 0 from F = -ky; solution y = A sin(omega t + phi)
- Graphs of displacement, velocity and acceleration in SHM
- Time period of a simple pendulum and of a mass on a spring (horizontal and vertical) - derivations
- Kinetic and potential energy in SHM; conservation of total energy; graphs of U, K and E against displacement
