In measuring time period of a pendulum, it is advised to measure the time between consecutive passage through the mean position in the same direction. This is said to result in better accuracy than measuring time between consecutive passage through an extreme position. Explain.
Answers
Explanation ⇒ Physics is the subject of the Accuracy. A Smaller mistake may leads to the larger difference in the answer.
While measuring the time period of the simple pendulum, it is advised to measure the time period from the mean position. This is because, by measuring from the means position, it becomes easy to note the no. of oscillations which the pendulum will make.
There are two extreme positions, and the person may get confused about the position which he chooses. But there is only one mean position, and by only noting the direction in which we are pushing the pendulum, our experiment can be completed with more accuracy.
Hope it helps.
We are confident about the mean location if we use pause watch to calculate the time between the consecutive section.
Explanation:
- The mean place of a particle performing simple harmonic motion is constant, while its extreme position tends to change.
- So we are confident about the mean place if we use pause watch to calculate the time between the consecutive section.
Harmonic motion :- Simplistic harmonic motion is a specific type of continuous periodic oscillation or motion in which the restorative force is directly related to the displacement and operates in the opposite direction to that of displacement.
