Introduction to Oscillations
Oscillations describe repeated motion about a mean position. This chapter builds the language of displacement, amplitude, period, frequency and phase.

Oscillations
Master SHM, springs, pendulum motion, phase and energy in oscillations.
CBSE
NEET
JEE Main
JEE Advanced
Periodic Motion Overview
Periodic motion repeats after equal intervals of time. Pendulums, vibrating springs and rotating systems help students recognize periodic patterns quickly.
Simple Harmonic Motion Overview
Simple harmonic motion occurs when the restoring force is directly proportional to displacement and opposite in direction.
SHM Equations Overview
SHM equations connect displacement, velocity, acceleration, angular frequency and phase. They make graphs and numerical problems easier to handle.
Energy in SHM Overview
In ideal SHM, kinetic energy and potential energy interchange continuously while total mechanical energy remains constant.
Damped and Forced Oscillations Overview
Damping reduces amplitude with time, while forced oscillations are driven by an external periodic force. Resonance appears when energy transfer is maximum.
