Answer:
What is the distance time graph for uniform motion?
For uniform motion, the distance-time graph is a straight line parallel to the time axis as speed will be constant. 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.
