Oscillations & Special Theory of Relativity

UG Physics (Honours) Notes 🔹 1️⃣ Oscillations ⭐ Simple Harmonic Motion (SHM) A body performs SHM when acceleration is directly proportional to displacement and directed towards the mean position:a=−ω2xa = -\omega^2 xa=−ω2x General solution:x(t)=Acos⁡(ωt+ϕ)x(t) = A\cos (\omega t + \phi)x(t)=Acos(ωt+ϕ) ⭐ Resonance Maximum amplitude occurs at:ω=ω0=km\omega = \omega_0 = \sqrt{\frac{k}{m}}ω=ω0​=mk​​ Quality Factor: Q=ω02γQ = \frac{\omega_0}{2\gamma}Q=2γω0​​ … Read more
