VIBRATION

      WHAT IS VIBRATION?

A vibration is the motion of the object that are moving back and forth of an object passing through a balance position . The oscillating motion is called a Vibration





EXAMPLES OF VIBRATION MOTION:
these are the common examples of vibration such as the following:


                                                 1.     Vibration of a pendulum

A swinging Pendulum

                  
                                                     2.    Vibration of a plastic ruler

3.    Vibration of a spring


a spring makes vibration


            CALCULATION OF VIBRATION / HOW TO KNOW THE MOTION OF VIBRATION

a swinging pendulum


Vibration is calculated by how many times the object moves back and forth. For Example:

 The motion is : 1 - 2 -3 - 2 - 1

*A motion of one vibration is always 4 counts, and we do not count the first one as it is the original position of the object and where the vibration starts from.*


OTHER EXAMPLE OF VIBRATION MOTIONS:

a vibration of...........

1/2:       1 - 2 - 3

1/4:       1 - 2

3/4:      1 - 2 - 3 - 2
