Question

write the deriation of 1st equation of the motion by velocity -time graph​

Answer 1

Answer:

considered the object moving in a straight line having uniform acceleration .a,u,v means final velocity and t,is the time taken.the velocity time graph of the object is shown below

Explanation:

From the graph

OA=U,BC=V

BC=BD+CD

CD=BC-BD

CD=V-U

a=change in velocity÷time taken

a=CD÷t

a=v-u÷t

at-u=v

v=u+a×t , 1st equation of motion
