Question

Define damped vibrations.

Answer 1

Damped vibrations:

1. Damped vibrations are periodic vibrations with a continuously diminishing amplitude in the presence of a resistive force.
2. The frictional forces(or resistive forces) act in the direction opposite to vibration.
3. The vibrations gradationally drop in frequency or stop, and the system returns to its original state of balance.
4. Example: Vibrations of a simple pendulum in air.
