Equation for Velocity – Time relation by graphical method – First equation of Motion

Let an object is moving with uniform acceleration.

Velocity Time Graph4
Let the initial velocity of the object = u

Let the object is moving with uniform acceleration, a.

Let object reaches at point B after time, t and its final velocity becomes, v

Draw a line parallel to x-axis DA from point, D from where object starts moving.

Draw another line BA from point B parallel to y-axis which meets at E at y-axis.
