If an object undergoes equal changes in velocity in equal intervals of time, then its motion is called uniformly accelerated motion.

A velocity-time graph gives the magnitude of displacement by calculating the area under the graph.

Consider the velocity-time graph of a body moving with uniform velocity.

Area under the graph = area ABCD

                                  = BC x AB

Assuming that line AB coincides at v m/s at the velocity axis and the DC = t s

Area under the graph = v x t

By definition: speed x time = magnitude of displacement.

Thus, the area under the velocity-time graph gives the magnitude of displacement.
