Question

Why is the distance-time graph for non-uniform motion curved?​

Answer 1

Answer:

Non-uniform motion is defined as the motion of an object in which the object travels with varied speed and it does not cover the same distance in equal time intervals, irrespective of the time interval duration.

The distance-time graph for non-uniform motion is not a straight line since speed is variable, it can be a curve or a zigzag line.

Answer 2

Answer:

For a uniform motion distance time graph is a straight line.

For non uniform motion it is curved because speed in variable. The line can even be zig Zag.
