Oscillations

• Phase difference

  Difference in patters of oscillation between two points.
• Conditions for simple harmonic motion

  1. acceleration is proportional to displacement

  2. acceleration acts towards the equilibrium position
• how do you get resonance

  when a SHO is driven of its natural frequency, it leads to large amplitude oscillations
• how do you calculate phase difference

  change in time/ T period X 2pie
• In SHM what should the force change with

  Resultant force is proportional to displacement, and oppose motion
