2. Principles of Damped Oscillations

Damped oscillations refer to a type of oscillatory motion where the amplitude of oscillation decreases over time due to energy loss, typically from friction or resistance. The general form of a damped oscillation can be described by the equation:

where:

x(t) is the displacement at time
A is the initial amplitude,
b is the damping coefficient,
m is the mass of the oscillating system,
ω is the angular frequency,
ϕ is the phase angle.

In this equation, 

represents the exponential decay of the amplitude over time, which characterizes the damping effect.
