Question

The motion of an object is plotted by four distance-time graphs. Which of the following graphs given below correctly describe the possible motion of the object?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

Correct Answer: Option(d)

Step 1: Explanation of the correct option

1. The graph in option d is in between distance and time.
2. In this graph, the distance increases uniformly with the increase in time.
3. So we can say that in this motion the object is moving at a constant speed.

Step 2: Explanation for wrong options

1. The graphs in options a and b can not represent a motion of an object because we can get two distances for one instant of time which is practically not possible.
2. The graph in option c can not represent a motion of an object because at an instant of time distance of an object can not increase suddenly.

The graph in option c can represent the possible motion of an object.
