Oscillations

In the NCERT Physics book Physics Part 2 (Class 11, Chapter – “Oscillations”), you explore the motion of objects that move back and forth around an equilibrium position. You learn about periodic motion and oscillatory motion, which occur in many natural and mechanical systems.

You study simple harmonic motion (SHM), where a restoring force acts on an object to bring it back to its equilibrium position. The chapter explains important quantities such as time period, frequency, angular frequency, amplitude, and phase.

You also learn how energy changes during oscillatory motion, switching between kinetic and potential energy as the object moves. Through this chapter, you develop the ability to analyze different types of oscillations and understand their applications in many physical systems.
