Question

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 slope of distance-time graph is a straight line parallel to time axis, the object is at the same position as the time passes. That means the object is at rest.

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.
