How can you find the distance travelled by a body in uniform motion from the velocity$-$time graph?

State whether the following statement is true or false:
Kinematics deals with the motion of non-living objects without taking into account the cause of their motion.

Account for the following:
$(a)$ Name the quantity which is measured by the area occupied below the velocity$-$time graph.
$(b)$ Give an example of an object moving in a certain direction with acceleration in the perpendicular direction.
$(c)$ Under what condition is the magnitude of average velocity of an object equal to its average speed?
$(d)$ Give an example of uniformly accelerated motion.
$(e)$ $A$ body is moving along a circular path of radius $r$. What will be the distance and displacement of the body when it completes half a revolution?

The displacement-time graph of a body is parallel to the time axis. What will you infer about the velocity of the body?

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

Name the physical quantity which corresponds to the rate of change of momentum.
