expain the meaning of the following free oscillation, damped oscillation, forced oscillation, maintained oscillation and resonant oscillation
Answers
Answer:
Free Oscillation
- Free oscillation is the oscillation of the particle with a fundamental frequency under the influence of restoring force.The free oscillation possesses constant amplitude and period without any external force to set the oscillation.
Damped Oscillation
- The damping is a resistance offered to the oscillation. The oscillation that fades with time is called damped oscillation. Due to damping, the amplitude of oscillation reduces with time.
Forced Oscillation
- When a body oscillates by being influenced by an external periodic force, it is called forced oscillation.
Maintained Oscillation
- Supplying energy from outside at the same rate at which the energy is losed by it, then its amplitude can be maintained constant & the system oscillates with its own natural frequency.
Resonant oscillation
- If a periodic force is applied on an oscillating body such that the frequency of applied force is equal to or integral multiple of the natural frequency of the oscillating body then the amplitude of oscillation becomes very large such oscillations are named as Resonant oscillations.
