Question

Distinguish between damped vibration and free vibration and forced vibration

Answer 1

Free Vibration:  A body oscillates with a constant frequency on its own (without the aid of any external force).

Forced vibration: A body oscillates with a constant frequency because of the application of an external force on it.

Damped vibration: A body whose amplitude of oscillation decreases over time.

Answer 2

Answer:

free vibration : they can only be produced in vacuum .

                        they don't have any opposing force .

damped vibration : they are produced in the presence of air or any medium .

                               they have an opposing force stopping the body from               vibrating .
