Oscillations — Class 11 CBSE Physics revision notes
A 4-page visual revision sheet for Oscillations, written for Class 11 CBSE Physics. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Oscillations sheet covers
- Periodic and oscillatory motion
- Simple harmonic motion, the one condition
- SHM equations
- displacement
- velocity
- acceleration
- SHM as a projection of circular motion
- The two extremes of a swing
- At the centre, x = 0
- At an extreme, x = ±A
- Period of a spring-mass system
- angular frequency
- period
- Energy in SHM
- Energy formulas
- kinetic energy at displacement x
- potential energy at displacement x
- total, any instant
- Speed at half the amplitude
- Simple pendulum
- Simple pendulum, the numbers
- Springs in combination
- in series
- in parallel
- Damped oscillations
- Damped oscillation, the equation
- displacement, damping constant b, mass m
- the amplitude envelope
- Forced oscillations and resonance
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Physics chapter by chapter against your real exam dates and free hours, and when the plan reaches Oscillations the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
