Question

In the science class, Drishti observed a video showing the working of a pendulum wall
clock. She noted that a slight change in the initial displacement of the (bob) did not
affect the time period of the pendulum. When she discussed her observation with her
grandfather, he told her that we must also not let the effects of small disturbances to
change the daily routine and the values of our life.
Now,
Design an activity to show that a slight change, in the initial displacement of the
bob, does not affect the time period of a simple pendulum.​

Answer 1

Answer:

This is how the initial displacment of the bob

Explanation:

The length of the pendulum and, to a lesser extent, its weight distribution (the moment of inertia about its own centre of mass) and swing amplitude (width) all affect the period. Its length at standard gravity is 0.994 m. (39.1 in).

A basic pendulum is a machine in which the point mass is hung from a fixed support by a light, inextensible string. The mean position of a simple pendulum is shown by a vertical line flowing through a fixed support. The length of the simple pendulum, abbreviated L, is the vertical distance between the point of suspension and the suspended body's centre of mass (when it is in mean position). The resonant mechanism supporting this type of pendulum has a single resonant frequency. A straightforward pendulum is a mechanical device that exhibits periodic motion. The basic pendulum consists of a tiny mass "m" bob hung on a thin string that is fastened to a platform at its upper end.

A mechanical device that oscillates or sways is known as a simple pendulum. The gravitational force is primarily responsible for this motion, which takes place in a vertical plane. It's interesting that the bob hung at the end of the thread is so light that in certain ways we might almost argue it has no mass. By lengthening the rope and measuring from the point of suspension to the middle of the bob, a simple pendulum's period can be prolonged. It should be noted, though, that if the bob's mass is altered, the period will remain constant. Since the strength of the gravitational field is not constant, the pendulum's position in regard to the Earth has the greatest impact on period.
