how would the d-t graph be for an object moving in a circular motion ?

Suppose an athlete takes t seconds to go once around the circular path of radius r, then the velocity v is given by the relation
distance travelled = circumference of the circle
= 2p r
The following table gives the distance covered by a bus after every 15 minutes.
|Distance covered in Km||0||5||15||20||25||30||35|
|Time in Minutes||0||15||30||45||60||75||90|
the motion is non-uniform i.e., it covers unequal distances in equal intervals of time.
Nature of S- t Graph for Non- Uniform Motion and Uses of Graphs
Let us now see the nature of S-t graph for non-uniform motion.
Nature of s-t Graph for Non-uniform Motion
Fig (a) represents the S-t graph when the speed of a moving object increases and Fig (b) represents the S-t graph when the speed of a moving object decreases.
From the nature of S-t graph we can conclude whether the object is moving with uniform speed or variable speed.
