Question

Is motion uniform for a moving body when its distance time graph is a straight line?​

Answer 1

yes, motion is uniform for a moving body when its distance time graph is a straight line.

Answer 2

Answer:

Distance-Time Graph for Uniform Motion

Let us now consider a distance-time graph in which the body is moving with uniform motion. A body is said to be in uniform motion when the body covers the equal distance in equal time intervals. Let’s consider a time interval of 1 second, If a body covers 10 meters in the first 1-second then it should cover 10 meters in every second from there on, this will indicate that the body is in uniform motion. Let’s draw a graph for uniform motion.

As in uniform motion, the distance time graph would be a straight line, because the equal distance is covered in equal units of time.

Distance Time Graph

You can see that there are three bodies A, B and C, all of them are in uniform motion then why do they have different slopes?

It is because the slope of a distance-time graph determines the speed of that body, so steeper the slope greater will be the speed of the body. From the above graph, we can come to a conclusion that body A has the highest speed and body C has the least speed.
