The distance-time graph of a body is a straight line inclined to the time axis. The body is in:

$A$ truck is moving on a straight road with uniform acceleration. The following table gives the speed of the truck at various instants of time.

Speed $(m s^{-1})$	$5$	$10$	$15$	$20$	$25$	$30$
Time $(s)$	$0$	$10$	$20$	$30$	$40$	$50$

Draw the speed-time graph by choosing a convenient scale. Determine from it:
$(i)$ The acceleration of the truck.
$(ii)$ The distance travelled by the truck in $50$ seconds.

If the displacement $-$ time graph for a particle is parallel to the time axis, what is the velocity of the particle?

Four cars $A$,$B$,$C$ and $D$ are moving on a levelled road. Their distance versus time graphs are shown in the figure. Choose the correct statement.

What is the nature of the displacement-time graph of a body moving with constant velocity?

What conclusion can you draw from the displacement$-$time graph of a body as shown below?
