What factors affects the pendulum?

Answer 1

There are a number of things that affect the pendulum and how it operates. Let's just start setting them down. The mass of the pendulum and its string, cable, rod, or whatever it is that it is suspended from. The length of the suspension cable or rod. The nature of the pivot point from which the suspension is tied, or, more specifically, the friction generated by the pivot. The air resistance to the pendulum and its suspension. The latitude at which it is operated (because a small amount of torque will be applied at anything more than 0o). The nature and loss of the driving mechanism for the continued movement of the pendulum. The temperature of the surrounds of the pendulum and its mechanism.
