{{ :fsc-pctb-11:notes:fsc-pctb-11-notes-ch06.jpg?nolink&600|Chapter 07: Oscillations}}
This is a seventh chapter of the book Physics 11 published by Punjab Curriculum and Textbook Board, Lahore, Pakistan.

After studying this chapter the students will be able to:

  * Investigate the motion of an oscillator using experimental, analytical and graphical methods.
  * Understand and describe that when an object moves in a circle the motion of its projection on the diameter of the circle is simple harmonic. 
  * Show that the motion of mass attached to a spring is simple harmonic.
  * Understand that the motion of simple pendulum is simple harmonic and to calculate its time period.
  * Understand and use the terms amplitude, time period, frequency, angular frequency and phase difference.
  * Know and use of solutions in the form of $x=x_0 \cos \omega t $ or $y=y_0 \sin \omega t $.
  * Describe the interchange between kinetic and potential energies during SHM.
   * Describe practical examples of free and forced oscillations.
  *Describe practical examples of damped oscillations with particular reference to the effects of the degree of damping  and the importance of critical damping in cases such as car suspension system.
