The formula for the frequency of the pendulum is w2=g/l

if you wish to double your period w1, you want to have w2 = 2*w1

The needed length of the pendulum is then l2 = g / w22 = g /(4 * w12) = 0.25 * g / w12 = 0.25 * l1

l2 / l1 = 1/4

You must shorten the length of the pendulum to 1/4 of its former size.

When the length of a pendulum increases what will it effect on the time period?

The period is proportional to the square root of the length so if you quadruple the length, the period will double.


What effect does shortening the length of the pendulum have on the period of the pendulum?

A shorter pendulum has a shorter period. A longer pendulum has a longer period.


How does length effect the period of a pendulum?

A longer pendulum has a longer period.


What is the length of a pendulum with a period of 1.49 s?

pendulum length (L)=1.8081061073513foot pendulum length (L)=0.55111074152067meter


What happen to the time period if its lenght of the pendulum is changed?

If the length of a pendulum is increased, the pendulum will take longer to complete a swing, and the clock will slow down. Shortening the pendulum will speed up the clock.


In simple pendulum if string is flexible then what is effect on time period?

multiply the length of the pendulum by 4, the period doubles. the period is proportional to the square of the pendulum length.


How does the period of a pendulum change for length?

A longer pendulum has a longer period. A more massive pendulum has a longer period.


How can you increase the period of a pendulum?

Increase the length of the pendulum


How does the period of a pendulum difference theoretically with length for simple pendulum?

The period is directly proportional to the square root of the length.


What happens to the period of a pendulum when the mass is doubled?

When the length of a pendulum is increased, by any amount, its Time Period increases. i.e. it moves more slowly. Conversely, if the length is decreased, by any amount, its Time Period decreases. i.e. it moves faster.


What does the period of a pendulum depend on?

The length of the pendulum and the gravitational pull.


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.
