NCERT CLASS IX - Science Textbook
Chapter 8 - Motion

What can you say about the motion of an object whose distance - 'time graph is a straight line parallel to the time axis?

Answer 1

When the distance - time graph is a straight line parallel to the time axis, that means that  the distance traveled remains a constant wrt time.

The position of the body at any time is same with respect to the initial position or origin at time = 0.

So the body is at rest.  its speed and velocity are zero.

Answer 2

Answer:

If the distance time graph of an object is a straight line parallel to the time axis, it shows that the distance of the object from its starting position is just the same at all times. Since the remains at same position from the starting position, it is not moving. The object is stationary.
