The branch of Physics which deals with the motion of objects while taking into consideration the cause of motion is

How will the equations of motion for an object moving with a uniform velocity change?

Prove that if a body is thrown vertically upward,the time of ascent is equal to the time of descent.

What is meant by uniform motion? Can you think of an example of a body in uniform motion?

$A$ 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.

The velocity-time graph (Fig.) shows the motion of a cyclist. Find $(i)$ its acceleration $(ii)$ its velocity and $(iii)$ the distance covered by the cyclist in $15\,s$.
