Any terminal object such as the weight on a pendulum is known as a Bob. It can also be called a Mass
-- its length (from the pivot to the center of mass of the swinging part) -- the local acceleration of gravity in the place where the pendulum is swinging
The weight on a pendulum is a 'mass' or a 'bob'.
To slow down a swinging clock pendulum, one must make it longer. In mechanical clocks, the majority of the mass of the pendulum is contained in the "bob" (a disk or weight) usually at the bottom of the pendulum. If you lower the pendulum bob, the pendulum is lengthened and the pendulum runs slower. This is usually done by turning a nut on a threaded portion of the pendulum just below the bob. Make sure the bob drops as you lower the nut or nothing will change. To raise the rate of the pendulum (make it run faster), you just turn the nut the opposite way.
The weight of the 'bob' doesn't, as long as the distance fromthe pivot to the swinging center of mass doesn't change.
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.

Answer: The combined inertia of the arm and pendulum would alter the energy characteristics of the system and throw off the timing. Answer: If the mass of the arm is not negligible, then you can no longer assume (as in an ideal pendulum) that the entire mass is concentrated in the swinging object at the bottom. The center of mass would be higher up. Exactly how high depends on the characteristics of the pendulum; details can be calculated with integral calculus.

Assuming that this question concerns a pendulum: there are infinitely many possible answers. Among these are: the name of the person swinging the pendulum, the colour of the pendulum, the day of the week on which the experiment is conducted, the mass of the pendulum, my age, etc.

The simple pendulum model does not take into account some factors that affect actual pendulums. It is a close approximation in many cases. The formulas are much simpler than the formulas for the actual motion of the pendulum. That's why it's called simple. But if the 'swinging angle' is too large the simpler formulas are no longer accurate. Also if the rod, which the pendulum is suspended on, has too large a mass in relation to the pendulum weight, then the simple formulas won't work.
The period of oscillation of a simple pendulum displaced by a small angle is: T = (2*PI) * SquareRoot(L/g) where T is the period in seconds, L is the length of the string, and g is the gravitional field strength = 9.81 N/Kg. This equation is for a simple pendulum only. A simple pendulum is an idealised pendulum consisting of a point mass at the end of an inextensible, massless, frictionless string. You can use the simple pendulum model for any pendulum whose bob mass is much geater than the length of the string. For a physical (or real) pendulum: T = (2*PI) * SquareRoot( I/(mgr) ) where I is the moment of inertia, m is the mass of the centre of mass, g is the gravitational field strength and r is distance to the pivot from the centre of mass. This equation is for a pendulum whose mass is distributed not just at the bob, but throughout the pendulum. For example, a swinging plank of wood. If the pendulum resembles a point mass on the end of a string, then use the first equation.
Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.
The mass at the end of the pendulum is the bob
Assuming an idealised pendulum with a small amplitude, both are examples of simple harmonic motion. That is, the second derivative of the curve is directly proportional to its displacement but in the opposite direction. If the amplitude (swing) of the pendulum is large or if the majority of its mass is not oi the "blob" the relationship is only approximate.
