Difference between Forced Oscillation and Resonance
Forced Oscillation and Resonance are two terms used in physics, specifically in the study of oscillations and vibrations.
The main difference is that the forced oscillation is the oscillation of a system when an external force is applied to it while resonance is the amplification of an oscillation when the frequency of the external force matches the natural frequency of the system.
Before we move to the differences, let’s understand what are Forced Oscillation and Resonance:
- Forced Oscillation: Forced Oscillation is the oscillation of a system when an external force is applied to it. The external force can be a steady or periodic force, such as a push or pull, and the system will respond to the force by oscillating at a certain frequency.
- Resonance: Resonance is the amplification of an oscillation when the frequency of the external force matches the natural frequency of the system. When this happens, the system will respond to the force by oscillating at a greater amplitude.
Now, let’s move to Forced Oscillation vs Resonance:
Major differences between Forced Oscillation and Resonance
| Forced Oscillation | Resonance |
|---|---|
| Forced Oscillation is the oscillation of a system when an external force is applied to it. | Resonance is the amplification of an oscillation when the frequency of the external force matches the natural frequency of the system. |
| Forced Oscillation can occur at any amplitude. | Resonance results in a greater amplitude of oscillation. |
| Forced Oscillation can be produced by any external force. | Resonance is dependent on the natural frequency of the system. |
| Forced Oscillation is a common phenomenon. | Resonance is a specific type of phenomenon. |
| Forced Oscillation can be observed in various systems. | Resonance is observed in specific types of systems, such as mechanical, electrical, and acoustic systems. |
That’s it.
Note that sometimes, the question might also be asked as “distinguish between Forced Oscillation and Resonance”.
