Difference between Free and Forced Vibrations

1. When a body vibrates with its natural frequency and time period which is the characteristic of the body itself, it is said to have free vibrations. When a body is set into vibrations with the help of a strong periodic force then vibration is said to be forced vibration. The frequency of forced vibrations may not be equal to the natural frequency of the body.

2. It is difficult to realize Free vibrations in practice. They can take place only in a vacuum. Forced vibrations can be realized in practice.
