The mass at the end of the pendulum is the bob
The weight on a pendulum is a 'mass' or a 'bob'.
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.
Any terminal object such as the weight on a pendulum is known as a Bob. It can also be called a Mass
Not at all, as long as the mass of the 'bob' is large compared to the mass of the string.
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.

Not in the theoretical world, in the practical world: just a very little. The period is determined primarily by the length of the pendulum. If the rod is not a very small fraction of the mass of the bob then the mass center of the rod will have to be taken into account when calculating the "length" of the pendulum.

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.
The bob is the weight on the end of the pendulum.
According to the mathematics and physics of the simple pendulum hung on a massless string, neither the mass of the bob nor the angular displacement at the limits of its swing has any influence on the pendulum's period.
No, it does not. The earth's acceleration is relatively constant at or near the surface; about 9.8 meters per second squared. In short, just because the mass of an object is more or less does not mean it can affect the gravitational force of the earth. ================================= I think you may be asking whether the mass of the pendulum bob affects the result of the MEASUREMENT when we use that pendulum to measure the local acceleration of gravity. There again, the answer is No ... When you look at the formula that relates the period of the pendulum, its length, and the local gravity, the mass of the pendulum doesn't appear in the formula, and the result of the calculation is the same no matter how heavy your bob is. Now, if you want to get technical about it, the 'length' of the pendulum is the distance from the pivot to the center of mass. So, if the string or other means of suspension from which the bob hangs is NOT massless, then the mass of the bob does affect the position of the center of mass, and therefore the period of the pendulum. So for accurate measurement, it's always best to use the lightest possible string, and the most massive possible bob, in order to have the center of mass actually located as close as possible to where you THINK it is.
That's an "idealized" pendulum, which is completely rigid, and where all the mass is concentrated in the bob, which is considered to be pointlike.
