what periodic motion is used as a reference for our year
help will be greatly appreciated

Periodic motion is any motion that repeats itself in a regular pattern over a certain period of time. It can be described by its amplitude, frequency, and period. Examples of periodic motion include the swinging of a pendulum and the rotation of planets around the sun.
Periodic motion follows a specific pattern and has a predictable outcome, while random motion does not have a specific pattern and its outcome is unpredictable. Additionally, periodic motion is often caused by some type of force or energy acting on an object, while random motion is usually the result of external factors such as collisions or fluctuations in a system.
Frequency and period are inversely related in periodic motion. Frequency is the number of complete cycles of a motion that occur in one second, and is measured in Hertz (Hz). Period is the time it takes for one complete cycle of the motion, and is measured in seconds (s). The formula for this relationship is: frequency = 1/period.
Some real-life examples of periodic motion include the oscillation of a spring, the vibration of guitar strings, the rotation of the Earth around its axis, and the swinging of a child on a swing. Other examples include the pulsing of a heart, the movement of a pendulum clock, and the rotation of a washing machine during the spin cycle.
Periodic motion is utilized in many modern technologies, such as in clocks and watches to keep time, in musical instruments to produce sound, and in engines to convert linear motion into rotational motion. It is also used in seismology to measure earthquakes, in radar to detect objects, and in medical devices such as pacemakers and ultrasound machines.
