# The concept and examples of the oscillatory motion

### The periodic motion

The periodic motion is a motion which is regularly repeated in equal periods of time, The oscillatory motion and the wave motion are examples of the periodic motion.

#### The oscillatory motion

The oscillatory motion is the motion of the oscillating body around its rest point, where the motion is repeated through the equal intervals of the time.

##### Examples of the oscillatory motion
• The clock, The tuning fork, The spring, The stretched string, The motion of the swing, The rotary bee.
• The movement of the Earth’s crust during the earthquakes.
• The movement of the atoms in the molecules.
##### Some concepts related to the oscillatory motion

The amplitude: the amplitude is the maximum displacement done by the oscillating body away from its original position, The measuring unit of the amplitude is metre or centimetre.

The complete oscillation: the complete oscillation is the motion of an oscillating body when it passes by a fixed point on its path two successive times in the same direction.

The periodic time: the periodic time is the time taken by an oscillating body to make one complete oscillation, The measuring unit of the periodic time is the second.

The frequency: the frequency is the number of the complete oscillations made by an oscillating body in one second, The relation between the periodic time and the frequency is an inverse relation.
