Mind Maps for SHM (Simple Harmonic Motion) Revision - Class 11, JEE, NEET

All SHM is oscillatory, but not all oscillatory motion is SHM. Oscillatory motion simply means back-and-forth movement. SHM is a special case where the restoring force is strictly proportional to displacement (F = −kx). A swinging pendulum at small angles approximates SHM; at large angles it does not.

There are roughly 15–20 core formulas in SHM for Class 11, covering displacement, velocity, acceleration, time period (spring and pendulum), kinetic energy, potential energy, total energy, and spring combinations. The two mind maps on this page organise all of them into two visual sheets so nothing is missed during revision.

Yes, SHM is consistently important for JEE Main. NTA typically includes 1–2 questions on Oscillations in every JEE Main session, often testing time period of spring-mass systems, energy graphs, or pendulum in non-inertial frames. Based on past papers, this chapter alone can contribute 8–16 marks across both sessions in a year.

Solved SHM problems are available in the NCERT textbook (Chapter 14 – Oscillations) and its solutions. You can access fully worked-out NCERT Solutions for Class 11 Physics on eSaral, which cover every exercise question with step-by-step explanations written by IIT-faculty. For additional practice, eSaral's question bank includes topic-wise SHM sets graded by difficulty.

The time period for a spring-mass system is T = 2π√(m/k), where m is the mass attached to the spring (in kg) and k is the spring constant (in N/m). This formula holds for both horizontal and vertical orientations because the effect of gravity cancels out in the vertical case when measured from the new equilibrium position.

Yes. The SHM formulas and concepts covered in these mind maps are identical for NEET Physics. The NEET syllabus follows NCERT Class 11 Chapter 14 (Oscillations) directly. Focus on spring-mass systems, simple pendulum, and energy graphs — these are the highest-frequency NEET SHM question types
