NCERT Grade 11 Chapter 14, Oscillations is the next step after learning about projectile motion, rectilinear motion and others in lower grades. The study of oscillatory motion is basic to physics; its concepts are required for the understanding of many physical phenomena. This chapter will help us to study in detail about oscillations and oscillatory motion.
The description of a periodic motion, in general, and oscillatory motion, in particular, requires some fundamental concepts, like period, frequency, displacement, amplitude and phase. These concepts are developed in this chapter. Along with; Periodic and Oscillatory Motions, Period and Frequency, Displacement, Simple Harmonic Motion, Simple Harmonic Motion and Uniform Circular Motion, Velocity and Acceleration in Simple Harmonic Motion, Force Law for Simple Harmonic Motion, Energy in Simple Harmonic Motion, Some Systems Executing Simple Harmonic Motion, Oscillations due to a Spring, Simple Pendulum, Damped Simple Harmonic Motion, Forced Oscillations and Resonance are explained in this chapter.
Laws based on Oscillations, numerical problems with solved and problems for practice, formulas to derive equations and solve problems, graphs, diagrams and theoretical explanations help to sail through the chapter and comprehend the learning experience. NCERT Grade 11 Chapter 14, Oscillations is a part of Unit X, Oscillations and Waves. Unit X has a weightage of 10 marks in the final examination of Grade 11 as per the latest pattern.
