What is the slope of the displacement $-$ time graph when the body has uniform motion ?

The slope of the line on a position-time graph reveals information about an object's velocity. What conclusion can you draw regarding the motion of an object, if the graph is a

$(i)$ Horizontal line.

$(ii)$ Straight diagonal line.

$(iii)$ Curved line.

Account for the following

$(a)$ Name the quantity which is measured by the area occupied below the velocity$-$time graph.

$(b)$ An object is moving in a certain direction with acceleration in the perpendicular directions.

$(c)$ Under what condition is the magnitude of average velocity of an object equal to its average speed ?

$(d)$ 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 revolution ?

Write true or false for the following statements

Motion along a curved line is called translatory or rectilinear motion.

State which of the following situations are possible and give an example of each of these

$(a)$ A body moving with constant acceleration but with zero velocity.

$(b)$ A body moving horizontally with an acceleration in vertical direction.

$(c)$ A body moving with a constant velocity in an accelerated motion.
