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.
