In actual conditions, a pendulum's motion can be seen as periodic, but decaying.
Gravity acts on the pendulum.
periodic
When something repeats like a pendulum.
A torsional pendulum exhibits rotational periodic motion. You can create one by hanging some weight from a cord, and then rotating the weight. The cord becomes twisted, generating a torsion force, that will cause the weight to rotate in the oppopsite direction. Thus, a periodic rotation movement is generated.

The period or frequency of the pendulum
When something repeats like a pendulum.
The frequency of a periodic motion refers to the number of cycles that are completed per second. The frequency is obtained by getting the reciprocal of the period.

The frequency of a pendulum is inversely proportional to the square root of its length. If you want to increase the frequency of a pendulum by a factor of 10, you make it 99% shorter.
The frequency depends on what the frequency is of. A pendulum or other simple harmonic motion has a constant frequency, a Poisson event has a variable frequency, although the long term average is a constant.
In the equation of a periodic motion it could represent the amplitude, frequency or phase.
Simple harmonic motion is non-complex periodic motion, just like the swing of a pendulum. The pendulum starts at the "top" of one side, swings down through the bottom of an arc, and then reaches the "top" of the other side. Once there, it swings back down through the bottom of its arc to the place it began. This is one complete cycle of the motion of that pendulum. What is characteristic of the motion is that is repeats, and there is a time interval associated with the movement. It takes some amount of time for the complete cycle to occur, and that is said to be the period of the motion. Additionally, if we look at the number of cycles of the motion for a given period of time, we could specify a frequency for that motion. It takes "x" seconds for one cycle (the period of the motion) to occur, or there are "z" cycles of that motion (the frequency of the motion) for a given span of time.All things considered, either frequency or periodcould be said to be a basic unit of simple harmonic motion.
Simple harmonic motion, In mechanics and physics, is a type of periodic motion where the restoring force is directly proportional to the displacement. A good example of this is a pendulum.
