Best Answer

Approximately 2*pi*sqrt(l/g) where

l is the length of the pendulum (in metres) and g = 9.8 ms-2, the acceleration due to gravity.

What variable controls the period of vibration of a pendulum?

Its length.


Does the length of pendulum affect the period of vibration?

Yes. Given a constant for gravity, the period of the pendulum is a function of it's length to the center of mass. In a higher gravity, the period would be shorter for the same length of pendulum.


How great is the period of a pendulum that takes one second to make a complete to-and-fro vibration?

The period of a pendulum that takes one second to complete a to-and-fro vibration is one second. This means it takes one second for the pendulum to swing from one extreme to the other and back again. The period is the time it takes for one complete cycle of motion.


How is the period of the pendulum affected by the amplitude of vibration?

Hardly at all, at small displacements or amplitudes. At larger displacements (larger angles), the period will get somewhat longer.


If a pendulum has a period of 1.5 seconds how long does it take to make a complete back and forth vibration?

A complete back and forth vibration, also known as a full oscillation, for a pendulum with a period of 1.5 seconds would take a total time of 3 seconds. This time includes both the movement to one side and back to the starting point.


How does the period of a pendulum change for length?

The period of a pendulum is directly proportional to the square root of its length. As the length of a pendulum increases, its period increases. Conversely, if the length of a pendulum decreases, its period decreases.


What is the period of a pendulum that takes one second to make a complete back and forth vibration?

The period of a pendulum that takes one second to complete a full oscillation is 2 seconds. Each back and forth swing (oscillation) consists of two periods, one forward and one backward. So, the total time for a complete back and forth vibration is 2 seconds.


What happen to period of pendulum when mass increase?

The period of a pendulum is not affected by the mass of the pendulum bob. The period depends only on the length of the pendulum and the acceleration due to gravity.


How does length effect the period of a pendulum?

A longer pendulum has a longer period.


How does height affect the period of a pendulum?

Height does not affect the period of a pendulum.


What happens to the period of a pendulum if you increase its mass?

Increasing the mass of a pendulum would not change the period of its oscillation. The period of a pendulum only depends on the length of the pendulum and the acceleration due to gravity, but not the mass of the pendulum bob.


What factor has the greatest effect on the period of a pendulum?

The length of the pendulum has the greatest effect on its period. A longer pendulum will have a longer period, while a shorter pendulum will have a shorter period. The mass of the pendulum bob and the angle of release also affect the period, but to a lesser extent.
