Physics Revision Notes for Class 11 Chapter 14 Oscillations

Class 11 Physics Revision Notes Chapter 14 Oscillations comprises all the related information with respect to this chapter. This note consists of very important topics of this chapter such as simple harmonic motion, kinetic energy, potential energy. But first, we should know what is oscillation and spring:

  • In a pendulum-driven clock, for example, the oscillation is the back and forth movement of the pendulum. Oscillators may be mechanical or electronic, but all work on the same principles
  • A spring is a mechanical device that produces a restoring force when stretched or compressed. The restoring force acts to restore the spring to its equilibrium position and is typically proportional to the displacement

Students will be seeing the connection of springs in series and parallel. The simple pendulum which uses the concept of oscillation is described comprehensively along with the definition of frequency and time period and speed etc. These notes are a must to have with regarding to preparation in exams.

Frequently asked Questions on CBSE Class 11 Physics Notes Chapter 14: Oscillations


What is meaning of ‘oscillatory motion’?

A motion repeating itself is referred to as periodic or oscillatory motion.


What is ‘resonance’?

Resonance describes the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force is equal or close to a natural frequency of the system on which it acts.


What is ‘acoustic sound’?

Acoustics is the science related to the production, control, transmission, reception and effects of sound.
