Damped oscillations
A velocity-proportional drag term added to the equation, the solution A₀e(−γt)cos(ω′t) with ω′ = √(ω₀² − γ²), the underdamped, critical, and overdamped regimes, energy decay and Q; linear drag is a model, and dry friction decays differently.

What this subsection covers
A velocity-proportional drag term added to the equation, the solution A₀e(−γt)cos(ω′t) with ω′ = √(ω₀² − γ²), the underdamped, critical, and overdamped regimes, energy decay and Q; linear drag is a model, and dry friction decays differently.A strong response uses amplitude and phase resonance curves and states where the model stops being reliable.
Reasoning checklist
Evidence, assumptions and limits
Assumptions to state
State the system, observable, approximation, and conditions held fixed before using a model.
Evidence to collect
How do the damping constant and the drive frequency reshape steady-state amplitude, phase lag, and the time the transient takes to die away?

How do the damping constant and the drive frequency reshape steady-state amplitude, phase lag, and the time the transient takes to die away? Useful evidence includes numerically integrated trajectories, an amplitude-versus-frequency sweep at several damping values, a phase-versus-frequency sweep tested against the π/2 crossing at ω₀, fitted peak positions and widths, and comparison with the linear-response prediction.

This GioPhysics course map is an adaptable learning sequence, not academic credit, accreditation, or a universal university syllabus. Third-semester content is the least standardised of the introductory sequence: departments place oscillations, waves, optics, and thermal physics differently, and the modern-physics units here are a bounded survey rather than a complete course in relativity, quantum mechanics, atomic, nuclear, or particle physics. Follow your institution's published scope, notation, laboratory programme, and assessment rules. A result should be checked against units, signs, limiting cases, and the conditions under which its model was derived.
