# What is First Equation of Motion

## First Equation of Motion

First Equation of Motion

Suppose an object moves with initial velocity ‘Vi” in a time “t” and covers a distance “S“ in an acceleration “a” and the final velocity of an object becomes “Vf

According to the definition of the acceleration “The rate of change of velocity is

called acceleration“

i.e. Acceleration = Change of velocity/time

=> a= Vf -Vi/t

DERIVATION

a = Vf – Vi/ t

at = Vf – Vi

or

Vf = Vi + at

Many authors defend their copyrights for their works, and they are perfectly correct in inviting us to buy a book in a store. And the speed of reading a “paper” book is higher than an electronic one. Again, the e-book lacks fields on which you can express your thoughts and take the necessary notes. Which in itself is an important skill. However, on this score, there are many different opinions on whether an electronic or paper version of the book is better. But we will not argue. Since today each of us chooses the option that suits him best.
