In a lightly damped oscillator, the period stays about the same but the amplitude gradually:
ADecreases
BDoubles
CDeepens
DDiverges
Answer & Solution
Correct answer: A. Decreases
1. Damping forces remove mechanical energy from the system.
2. Less energy means smaller swings.
3. So the amplitude gradually decreases.
