Define :(a) Free oscillations(b) Damped oscillations(c) Forced oscillations |
Answer» (a) Free oscillations: If a body, capable of oscillation, is slightly displaced from its position of equilibrium and then released, its starts oscillating with a frequency of its own. Such oscillations are called free oscillations. The frequency with which a body oscillates is called natural frequency. (b) Damped oscillations: The oscillations in which amplitude decreases gradually with the passage of time are called damped oscillations. (c) Forced oscillations: When a body oscillates under the influence of an external periodic force, not with its own natural frequency but the frequency of the external periodic force, its oscillations are said to be forced oscillations. |
