Question

Difference between free and forced vibration

Answer 1

hi
Forced Vibrations & Resonance. Free vibrations are oscillations where the total energy stays the same over time. This means that the amplitude of the vibration stays the same. ... If an object is being forced to vibrate at its natural frequency, resonance will occur and you will observe large amplitude vibrations.
hope it helps you

Answer 2

Answer:

2) Forced vibrations : The vibrations of a body in

response to an external periodic force are called

forced vibrations.

The external force supplies the necessary energY

to make up for the dissipative losses. The frequeney

of the forced vibrations is equal to the frequency of

the external penodic torce.

The amplitude of the forced vibrations depends

upon the mass of the vibrating body, the amplitude

of the external force, the difference between the

natural frequency and the frequency of the periodic

force, and the extent of damping.
