$(a)$ When will you say a body is in $(i)$ uniform motion $(ii)$ non-uniform motion?
$(b)$ Show the path of an object when it is in uniform motion with the help of a graph.

(N/A) $(i)$ $A$ body is said to be in uniform motion if it covers equal distances in equal intervals of time.
$(ii)$ $A$ body is said to be in non-uniform motion if it covers unequal distances in equal intervals of time.
$(b)$ For an object in uniform motion,the distance-time graph is a straight line passing through the origin,as shown below:
[Graph: $A$ straight line starting from the origin $(0,0)$ on a Cartesian plane where the y-axis represents 'distance' and the x-axis represents 'time'.]
