Question

distance time graph for constant velocity. Do we need to draw a straight line
​

Answer 1

Answer:

So, the distance travelled is directly proportional to time. When the two things are directly proportional to each other, then the graph drawn between them is a straight line. Thus, the distance-time graph of an object moving with a uniform speed (or constant speed) is a straight line.
