How is this vibration different from damped vibrations in terms of their amplitudes?
Topic: Natural and damped vibrations
Question wording verified against source paper
Answer
Exam answer
In ideal natural vibrations the amplitude remains constant, whereas in damped vibrations the amplitude gradually decreases with time.
Explanation
Damping removes mechanical energy through resistive forces.
