Question

What are the three parts of a pendulum? Describe each one please

Answer 1

The three parts of a pendulum is cable or wire, a bob or weight, and a fixed point. The fixed point is the starting point of where the wire hangs from and the weight is what's attached to the wire or the end point of wire. Depending on length of wire, the pendulum moves at a certain uniform speed.

Answer 2

Pivot point: It is the point around which pendulum oscillations occur.
Rope: Is one that is between the pivot point and the mass m. Thanks to the tension of the rope and its length, it is possible that oscillations of the pendulum occur.
Mass: is the one that is placed on the end of the rope of the pendulum.
The period of a pendulum is:
T = 2 * pi * root (l / g)
where,
l = length of the rope
g = gravity
