Question

state two advantages of plotting velocity time graph?

Answer 1

 two advantages of plotting velocity time graph are
-------------------------
1)its slope will give us the acceleration of the particle
2)the area under the graph will give us the displacement of the particle

Answer 2

In velocity time graph, time is taken on the X axis and Velocity is on Y axis.
From the velocity time graph , we can determine :

⇒The displacement of the body in a certain time interval :
   
     The area enclosed between velocity time graph gives displacement.
since displacement = velocity x  time

⇒The acceleration of the body :
       
           The slope of velocity time graph gives us acceleration.
           If slope is positive, it is accelerated motion.
           If slope is negative it is decelerated motion.
