When we say that the physics or any branch of it is an exact science by this we mean that , its laws are expressed in the from of mathematical equations which describe and predict the results of precise quantitative measurements.

## Galilean transformations

[latexpage]Motion is a relative concept. You are sitting on a train. An object on trains seems to be at rest from your perspective but it is in motion from the person standing on the ground. So it is tied to a particular frame of reference chosen by observer.Now Different observer may use the different frame …
