What is damped driven oscillator?

If a frictional force ( damping ) proportional to the velocity is also present, the harmonic oscillator is described as a damped oscillator. Driven harmonic oscillators are damped oscillators further affected by an externally applied force F(t).

What is meant by driven damped harmonic motion give an example?

When the motion of an oscillator reduces due to an external force, the oscillator and its motion are damped. These periodic motions of gradually decreasing amplitude are damped simple harmonic motion. An example of a damped simple harmonic motion is a simple pendulum.

What is driven harmonic oscillator?

From WikiLectures. A harmonic oscillator is a system in which an object vibrates with a certain amplitude and frequency. In a simple harmonic oscillator the are no extarnal forces, such as friction or driving forces working on the object.

What is quality factor of a damped harmonic oscillator explain its significance?

The energy loss rate of a weakly damped (i.e., ) harmonic oscillator is conveniently characterized in terms of a parameter, , which is known as the quality factor. This quantity is defined to be times the energy stored in the oscillator, divided by the energy lost in a single oscillation period.

What is forced harmonic oscillator discuss the characteristic of forced harmonic oscillator in detail?

A forced harmonic oscillator refers to a damped oscillator being subjected to an external force. When an external force is applied to an oscillator, it will undergo a transient state where the oscillator will shift from its natural frequency to the applied force’s frequency.

What are damped oscillations What is the cause of damping Class 11?

CBSE NCERT Notes Class 11 Physics Oscillations. Motion in which amplitude of the oscillating body reduces and eventually comes to its mean position. Dissipating forces cause damping. This implies that there is some resistive force which opposes the motion of the pendulum.

What is a driving force?

The impetus, power, or energy behind something in motion, as in He was clearly the driving force in the new administration. This term transfers the force that sets in motion an engine or vehicle to other enterprises.

What is the quality factor of an ideal oscillator?

In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is approximately defined as the ratio of the initial energy stored in the resonator to the energy lost in one radian of the cycle of oscillation.

What are damped and forced oscillations?

Damping occurs when a force is exerted on the oscillating object that causes the amplitude of its oscillations to get smaller and smaller over time. When an outside driving force is exerted on an object to make it oscillate at a certain frequency, the resulting oscillations are called forced oscillations.

Under what conditions does damped motion become oscillatory?

When the damping constant is small, b<√4mk b < 4 m k , the system oscillates while the amplitude of the motion decays exponentially. This system is said to be underdamped, as in curve (a). Many systems are underdamped, and oscillate while the amplitude decreases exponentially, such as the mass oscillating on a spring.
