Simple Harmonic Motion

Simple Harmonic Motion

1. -Acceleration is always acting towards the EQ or acceleration is in the opposite direction to displacement

   • -Acceleration is directly proportional to displacement from EQ position
     • -Force is always directly proportional to displacement from EQ position
       • -Force is always acting towards the EQ
         • a (is proportional to) -x

2. Oscilations

   • Free oscillation
     • Natural frequency
   • Forced oscillation
     • Driving frequency
       • Damping
         • Light
         • Heavy
     • Resonance

3. Constant time period even if the amplitude varies

4. Velocity is the greatest at the centre of the motion. I.e On a swing
