- The period of a pendulum is totally un-affected by the mass of the bob.
- The time period of pendulum is given by the eqn.

T=2*PIE*(l/g)1/2 ;l is the length of pendulum

;g is the acceleration due to gravity.

- 'l' is the length from the centre of suspension to the centre of gravity the bob.
- ie.the length of the pendulum depends on the centre of gravity of the bob,and hence the distribution of mass of the bob.

of course ... the length of the pendulum ... :) base on our experiment >>>

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.

Technically and mathematically, the length is the onlything that affects its period.

no ,because they are not the same

no. it affects the period of the cycles.

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.

Yes

No, but it affects the life of the bearings.

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.

Ideally, nothing. As long as the mass of the string is very small compared to the mass of the bob. The formula for the period of the pendulum doesn't even mention the mass of the bob.

The weight of the bob will determine how long the pendulum swings before coming to rest in the absence of applied forces. The period, or time of 1 oscillation, is determined only by the length of the pendulum.

Yes, the length of pendulum affects the period. For small swings, the period is approximately 2 pi square-root (L/g), so the period is proportional to the square root of the length. For larger swings, the period increases exponentially as a factor of the swing, but the basic term is the same so, yes, length affects period.
