Write the equation of motion and meaning of their symbol

There are three equation of motion first equation is according to the velocity time graph ,v= u+at in this equation v stands for final velocity U stands for initial velocity and a stands for acceleration and t stands for time taken the second equation of motion is according to distance time graph, s= ut+1/2at*t in this s stands distance u stands for initial velocity t stands for time taken t*t stands for t square and a stands for acceleration the third equation of motion is according to velocity distance graph, 2as= v*v-u*in this a stands for acceleration s stands for distance covered v*v stands for v square which is final velocity and U*U stands for u square which is initial velocity
