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

Changing the length of a pendulum or the mass of its bob has no effect on g; g is a constant, always equal to 9.8 meters per square second near the surface of Earth.

Assuming the pendulum referred to s asimple pendulum of an arm and a weight the major factors on the period are the local attraction of gravity and the length of the arm.

It doesn't. Period depends on the length of the pendulum and the acceleration of gravity. Adding weight doesn't change the period at all.

A simple pendulum with a length of 45m has a period of 13.46 seconds. If the string is weightless, then the mass of the bob has no effect on the period, i.e. it doesn't matter.

For relatively small oscillations, the frequency of a pendulum is inversely proportional to the square root of its length.

The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.

A longer pendulum has a longer period.

Yes, the length of a pendulum affects its swing. The oscillation will be longer with a longer length and shorter with a shorter length.

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

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

Changing the length will increase its period. Changing the mass will have no effect.

Changing the length of a pendulum or the mass of its bob has no effect on g; g is a constant, always equal to 9.8 meters per square second near the surface of Earth.

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

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

Assuming the pendulum referred to s asimple pendulum of an arm and a weight the major factors on the period are the local attraction of gravity and the length of the arm.
