The concept and examples of the oscillatory motion

The oscillatory mation

The oscillating body moves around its rest position , and the motion repeated through equal intervals .

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 pendulum

The simple pendulum

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 : You should know that 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 .

oscillatory motion

The periodic time is taken by an oscillating body to make one complete oscillation .

The complete oscillation : It is very important to know that 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 : You should know that 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 : It is very important to know that 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 .
