When there is a reduction in amplitude over every cycle of vibration, then the body is said to have

A free vibration
B forced vibration
C damped vibration
D none of the mentioned

Correct Answer: damped vibration

When no external force acts on the body, after giving it an initial displacement, then the body is said to be under free or natural vibrations. The frequency of the free vibrations is called free or natural frequency. When there is a reduction in amplitude over every cycle of vibration, the motion is said to be damped vibration.
