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

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

When an object is at rest, its distance-time graph is a straight line parallel to the time axis.

A straight line parallel to the x-axis in a distance-time graph indicates that with a change in time, there is no change in the position of the object. Thus, the object is at rest.

Our graph looks like

When the graph of a distance-time graph is a straight line parallel to time axis,

It means that distance remains same at any time.

So, the object does not move at any time.

Therefore, the body is at rest.

Text Solution

Solution : When distance-time graph of an object is a straight line parallel to the time axis, distance of the object at every instant of time is the same. Therefore, the object must be stationary.
