By /

Quick revision notes for Class 11 Physics Chapter 13 (Oscillations). These Class 11 Physics Chapter 13 notes are ideal for quick revision just before exams.

SHM Basics

  • Condition: a=−ω²x.
  • x=A sin(ωt+φ); v=Aωcos(ωt+φ); a=−Aω²sin(ωt+φ).

Energy

  • E=½mω²A² (constant); KE and PE interconvert.

Time Periods

  • Simple pendulum: T=2π√(l/g).
  • Spring-mass: T=2π√(m/k).

One-Line Summary

Oscillations describe periodic to-and-fro motion, with simple harmonic motion being the special case where restoring force is proportional to displacement, conserving total mechanical energy throughout.
