(i) The difference between uniform and non-uniform motion relies on, whether the velocity of the moving body is changing or not. If the velocity of the object changes to particular rate, then the motion is uniform, but if it increases or decreases at different points of time, then this movement is called as non-uniform motion.

(ii) In uniform motion, the object covers equal distance in equal time interval. In non-uniform motion, object covers equal distances in unequal time-intervals.
