The train moves with uniform velocity. Velocity-Time graph is just
parallel to x-axis. And the displacement increases with time as shown in the
next graph. The rate of change of displacement is constant and so
displacement-time graph is linear which is an indication of uniform

When velocity increases with time
, we say the body accelerates. Here the velocity of train increases with
the time . The rate of change of velocity with time is called acceleration. If
the rate of change of velocity with time is constant , it is the uniform
acceleration. In the velocity-time graph, it is seen that velocity increases
with time linearly. The slope of the line gives the magnitude of acceleration.
When a train starts from station, it increases its velocity by acceleration till
it reaches its maximum allowable velocity with which it further
moves as uniform velocity.
just opposite to that of acceleration. Here the velocity of the body decreases
with time. This happens when a train approaches a station where it is supposed
to stop and so it applies break in order to decrease its velocity to zero. The
velocity-time graph shows how velocity drops down with time.
