NEET Physics Damped & Forced Oscillations MCQ Question
Consider a diagram of a damped oscillator where a mass is attached to a spring and a damping force is acting on it. Which parameter specifically affects the rate at which the amplitude decreases over time in this system?
Damping constant
Mass of the oscillator
Angular frequency
Initial amplitude
Correct Answer
Detailed Explanation
According to the formula for displacement in a damped oscillator, x(t) = A e^(-bt/2m) cos(ω't + φ), the damping constant 'b' directly affects the rate at which the amplitude decreases over time.
