The periodic vibrations of a body of decreasing amplitude in presence of resistive force are called the damped vibrations.

Give one example of damped vibrations.
Example: Simple pendulum’s oscillation.
Name the phenomenon that causes a loud sound when the stem of a vibrating tuning fork is kept pressed on the surface of a table.
Resonance, when the frequency of an externally applied periodic force on a body is equal to its natural frequency, the body readily begins to vibrate with an increased amplitude. e.g. sympathetic vibrations of pendulums, frequency heard by tuning fork due to resonance with air etc.
