The graph given below is the distance-time graph of an object. Do you think it represents a real situation? Explain.

Answer:

No. The distance-time graph does not represent a real situation. This may be explained as follows: From A to B: Distance travelled increases with time. This situation is real. From B to C: Distance does not change with time. This means the body is at rest. This is also a real situation. From C to D: The portion of the graph shows that the object returns to position D earlier than it starts from C. This is not possible because time cannot be reversed. So, this part of the graph does not describe a real situation. Thus, the given distance-time graph does not represent a real situation.
