Question

state first equation of motion

Answer 1

HII DEAR ❤❤❤

FIRST EQUATION OF MOTION =============

______________________________________

Consider a body initial moving with velocity "Vi". After certain interval of time "t", its velocity becomes "Vf". Now

Change in velocity = Vf - Vi 
OR 
DV =Vf – Vi

Due to change in velocity, an acceleration "a" is produced in the body. Acceleration is given by

a = DV/t

 

Putting the value of "DV"

a = (Vf – Vi)/t
at = Vf – Vi
at + Vi =Vf




Hope it helps u.!⭐⭐⭐⭐

Answer 2

The equations of motion of kinematics describe the most fundamental concepts of motion of an object. These equations govern the motion of an object in 1D, 2D and 3D. They can easily be used to calculate expressions such as the position, velocity, or acceleration of an object at various times
