Simple Harmonic motion

Simple Harmonic motion

1. methods

   • for displacement
     • conservation of energy
       • specail case
   • for ω(angular frequency)
     • • and so throught the obtained equation on comparing the coefficients we can say ω
     • it is independent of force actin and depends only on the arrangement of the system ie even though force changes time period or angular frequency dosent change
     • write "F" as a linear function in "x" by assuming small changes in displacement..........(note thet during solving you must consider the component of force along which wave transmission takes place
       • Examples
     • Compoun Pendulum

2. Angular Simple Harmonic Motion

   • • here w depends only on k and I
   • restoring tourque τ=-kϴ

3. superimposition of two waves

4. Properties

   • x-t relation: Asinωt
