Revision Notes — Oscillations
Key concepts, formulas, and definitions from Oscillations for KCET Physics preparation.
Key Topics to Revise
13.1-13.2 Introduction and Periodic Motion
- Periodic motion repeats identically after fixed intervals (period T)
- Oscillatory motion is periodic motion confined between limits about a mean position
- Time period T is the smallest interval after which motion repeats
13.3 Simple Harmonic Motion (SHM)
- SHM is motion with acceleration proportional to displacement and directed toward equilibrium
- Standard equation: a = -ω²x (acceleration ∝ -displacement)
- Displacement equation: x(t) = A cos(ωt + φ)
13.4 SHM and Uniform Circular Motion
- SHM is the projection of uniform circular motion on any diameter
- Particle moving in circle of radius A with angular speed ω
- x-projection: x = A cos(ωt), y-projection: y = A sin(ωt)
13.5 Velocity and Acceleration in SHM
- Velocity: v(t) = -ωA sin(ωt + φ), maximum at mean position
- Acceleration: a(t) = -ω²A cos(ωt + φ) = -ω²x(t)
- Maximum velocity: vₘₐₓ = ωA (at x = 0)
