As we derive the expression for period using dimensional analysis,

we get T = 1/2pi ./(l/g)

In this no mass is present. Hence the conclusion

What is the relation between the mass and period of the pendulum?

The period is independent of the mass.


Is the period of a pendulum independent of mass?

Yes, mathematically. But it's really only true if the string has no mass at all.


What happens to time period of a simple pendulum if a heavy body is attached to it instead of bob?

The period of a simple pendulum is independent of the mass of the bob. Keep in mind that the size of the bob does affect the length of the pendulum.


What will happern to the pendulum if both the mass and length a increased?

Period of pendulum depends only on its length that too directly and acceleration due to gravity at that place, but inversely But it is independent of the mass of the bob So as length increases its period increases.


Which factor affects the period of the pendulum?

The period of a pendulum is affected by the angle created by the swing of the pendulum, the length of the attachment to the mass, and the weight of the mass on the end of the pendulum.


Does weight affect the swinging speed of a pendulum?

The period of the pendulum is dependent on the length of the pendulum to the center of mass, and independent from the actual mass.The weight, or mass of the pendulum is only related to momentum, but not speed.Ignoring wind resistance, the speed of the fall of objects is dependent on the acceleration factor due to gravity, 9.8 m/s/s which is independent of the actual weight of the objects.


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

The mass has no significant effect on the period.


What will be the effect of time period of a simple pendulum if its mass is doubled and its amplitude is halved?

The PERIOD of a Simple Pendulum is affected by its LENGTH, and NOT by its Mass or the amplitude of its swing. So, in your case, the Period of the Pendulum's swing would remain UNCHANGED!


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 factors affect the period of a pendulum?

In a simple pendulum, with its entire mass concentrated at the end of a string, the period depends on the distance of the mass from the pivot point. A physical pendulum's period is affected by the distance of the centre-of-gravity of the pendulum arm to the pivot point, its mass and its moment of inertia about the pivot point. In real life the pendulum period can also be affected by air resistance, temperature changes etc.


How much does a pendulum weigh?

A pendulum is a weight suspended from a pivot so it can swing freely. The period of swing of a simple pendulum depends on its length (how far the mass is from the pivot) and is is independent of the mass of the weight. This means that you do not need to worry about the weight except to say that it must be heavy enough not to be disturbed by air currents.


What happen to the time period of pendulum if the mass of bob is changed?

If you make the simplifying assumption that everything except the bob is massless, then the mass of the bob has no effect on the period.
