What is time period of a simple pendulum?
The time period of a simple pendulum: It is defined as the time taken by the pendulum to finish one full oscillation and is denoted by “T”. Length of a simple pendulum: It is defined as the distance between the point of suspension to the centre of the bob and is denoted by “l”.
What is the period of a 1’m long pendulum?
We are asked to find the period of a 1.00 meter long simple pendulum. So the formula for period is 2π times the square root of the length of the pendulum divided by acceleration due to gravity. So that’s 2π times square root of 1.00 meter divided by 9.80 meters per second squared which is 2.01 seconds.
Why is Kater’s pendulum better?
Kater’s pendulum was used as a gravimeter to measure the local acceleration of gravity with greater accuracy than an ordinary pendulum, because it avoids having to measure l. The relative gravimeter can then be carried to any location where it is desired to measure the acceleration of gravity.
Why is katers pendulum more accurate?
The point of suspension also is not accurately determined in a simple pendulum. So once a near equality in time period is obtained on both sides of the centre of gravity of the metallic bar, determining the length of the pendulum becomes more accurate, and so does determining the acceleration g due to gravity.
Why katers pendulum is called reversible?
A reversible pendulum is a special design of a normal physical pendulum. The reduction in the length of the pendulum then matches the distance between the two mounting points. This makes it easier to determine the local acceleration due to gravity from the period of oscillation and the reduced pendulum length.
Why bar pendulum is better than simple pendulum?
Advantages of bar pendulum over simple pendulum: is rigid, so motion is confined (mostly) to 2D; the string of the simple pendulum may not remain straight at maximum angular displacements, but there is no such problem with the bar pendulum (again assuming that it remains fairly rigid over the small angular …
Who invented katers pendulum?
captain Henry Kater
What is the function of pendulum?
Pendulum, body suspended from a fixed point so that it can swing back and forth under the influence of gravity. Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant.
