Why does amplitude of vibration decrease with time?

The amplitude of a vibrating body continuously decreases during damped vibrations because of the frictional (resistive) force due to the surrounding medium.

Why does the amplitude of a vibrating body decrease during a damped vibration?

Body continuously losses energy due to frictional force of the surrounding medium in damped oscillations, therefore the amplitude of body continuously decreases.

Does period depend on amplitude of vibrating body explain?

For a given pendulum ,the time period is the same every time. The time period of a pendulum depends only on the length of Pendulum. It does not depend on amplitude of vibrations.

What is amplitude of vibrating object?

Amplitude. A vibrating object moves to a certain maximum distance on either side of its stationary position. Amplitude is the distance from the stationary position to the extreme position on either side and is measured in metres (m). The intensity of vibration depends on amplitude.

What do you understand by free vibrations of a body?

Free vibration of the body is the kind of vibration when a force is exerted on the body only at once and the body starts to vibrate at its natural frequency.

What do you understand by free vibrations of a body 2?

Solution 2 The vibrations of a body in the absence of any external force on it are called the free vibrations. Eg.: When we strike the keys of a piano, various strings are set into vibration at their natural frequencies.

What is the meaning of amplitude in physics?

amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. The amplitude of a pendulum is thus one-half the distance that the bob traverses in moving from one side to the other.

What do you mean by amplitude and frequency of a vibrating object?

Solution: (a) Amplitude – The maximum displacement of a wave on either side of its mean position is called Amplitude. (b) Frequency – Number of oscillations made by a wave in one second is known as frequency.

What is amplitude class 8 short answer?

Explain What is Amplitude in Physics Class 8. Ans: The maximum displacement that is of an object which is vibrating from its Central position is known as the amplitude of vibration. The amplitude actually tells us how far the object which is vibrating is displaced from its central position.

How does the loudness depends on the amplitude of vibration?

Answer: Loudness of the sound produced by a vibrating object depends on the amplitude of vibration. Loudness is proportional to the square of the amplitude. Thus, if the amplitude is increased by three times, the loudness increases by nine times.

What is the amplitude of a vibrating object Brainly?

Answer: The size of a vibration or its amplitude is a measure of how far the object moves outwards from the starting position.

What is meant by free vibrations of a body what are forced vibrations?

In free vibration, energy will remain the same. The body keeps vibrating at the same amplitude. In forced vibration energy gets added to the vibrating body. The forced vibration is either damped or undamped.

How can we decrease the amplitude of vibration?

We can decrease the amplitude of Vibration by releasing the pendulum bob from a smaller height. One complete to and fro movement of the pendulum bob is called one vibration or one oscillation. The time taken by pendulum bob to complete one vibration or one oscillation is called the time period of pendulum.

What is amplitude of vibration of this simple pendulum?

The distance AB is the amplitude of vibration of this simple pendulum. The maximum displacement of a vibrating object from its Central position is called the amplitude of vibration. The amplitude actually tell us how far the vibrating object is displaced from its central position.

What are the three characteristics of vibration?

Every vibration or oscillation has three characteristics : Amplitude ,time period and frequency The maximum distance to which the bob of a vibrating pendulum goes from its central position is called amplitude of vibration or amplitude of oscillation The distance AB is the amplitude of vibration of this simple pendulum.

What do you mean by time period of vibration?

The time taken by a vibrating object to complete one vibration is called its time period. The time taken by one vibration or oscillation of a simple pendulum is very short and hence cannot be measured accurately. So to find the time taken by 1 vibrations we measure the time taken by a large number of vibration.
