MY Research 1st - Is This possible to express Speed in terms of Frequency

 Is This possible to express Speed in terms of Frequency...??

How did this click  in my mind?
===>>> 
                 One day I was driving my bike and suddenly other bike passed 
 near by me. when I focused on his bike's wheel which is moving then an Idea Clicked in my mind that was " wheel is moving that is it has some number of complete cycle per second.So Speed can express in terms of frequency.

   Now move on to work.First of all , As we know very well that 
                                           Speed = distance     and      its S.I unit is m/s.
                                                               time                            i.e   meter per second.
  let us consider a circle whose radius is 14 cm
   so its circumference will be    2⊼ r   = 2x(22/7) 14cm
                                                                          = 88cm

   Now suppose if a bike has a speed of 88m/s ..then here we how express the speed in terms of frequency.
    
                               Speed = 88m/s
                 or         Speed = (88) x 100 cm/s
                 or         Speed = (88cm) x 100/s
                 or         Speed = ( Circumference of wheel) x 100/s
                 or         Speed = ( one complete cycle) x 100/s
                 or         Speed = 100 cycle per sec
                 or          speed = 100 Hertz     { ( number of complete cycle per sec is                                                                                           frequency and its S.I unit Hertz (Hz) }

       Hence    speed can  express in terms of frequency.

                EXPRESSION FOR FREQUENCY 

                                 speed = Distance covered by a wheel
                                                                    time
                   or         speed = Circumference x number of revolution 
                                                                  second
                  0r         speed = n(2⊼ r)
                                                   sec
         So speed can be replace by Frquency 

                                                               Frequency =  n(2⊼ r)
                                                                                             sec  

                                          where ,  n = number of revolution
                                                           r  = radius of wheel
                                                 (2⊼ r)  =  circumference of wheel
     Please give me your feedback in comment box . My another research is              running  on how to generate electricity without using resources so get connect with me to get update of it.  Please like and share   your one share gives another a knowledge.

Physics online

Post your doubt and get appropriate answer of it..

Frame of Reference

In physics, a frame of reference (or reference frame) consists of an abstract coordinate system and the set of physical reference points that uniquely fix (locate and orient) the coordinate system and standardize measurements.

In n dimensions, n+1 reference points are sufficient to fully define a reference frame. Using rectangular (Cartesian) coordinates, a reference frame may be defined with a reference point at the origin and a reference point at one unit distance along each of the n coordinate axes.

In Einsteinian relativity, reference frames are used to specify the relationship between a moving observer and the phenomenon or phenomena under observation. In this context, the phrase often becomes "observational frame of reference" (or "observational reference frame"), which implies that the observer is at rest in the frame, although not necessarily located at its origin. A relativistic reference frame includes (or implies) the coordinate time, which does not correspond across different frames moving relatively to each other. The situation thus differs from Galilean relativity, where all possible coordinate times are essentially equivalent.
