Oscillations It's when a restoring force is proportional to the displacement from equilibrium.
Summary
F_x=-k\Delta x- Acceleration always points opposite to displacement.
- Equilibrium is where net force is zero.
- Maximum displacement is amplitude.
- Velocity is maximum at equilibrium.
- Pendulum acts as SHM at low angles because restoring force is proportional to angle.
