Answer 1

1. If a body covers equal distance in equal intervals of time along a straight line, howsoever small these intervals are, it is said to be in uniform motion.
2. The distance-time graph of a uniform motion is a straight line is shown below,

3. If a body covers unequal distances in equal intervals of time, howsoever small these intervals are, it is said to possess non-uniform motion.

4. The distance-time graph of non-uniform motion is shown below.
