Question

Which of the following figures represents uniform motion of a moving object correctly?

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The correct option is A

Explanation of correct option: In the case of option (A),

1. The slope of the distance-time graph is speed.
2. Uniform motion implies uniform speed and hence, a constant slope in the distance-time graph.
3. The graph in option (A) represents a constant slope graph and so it denotes uniform motion.

Explanation of incorrect options:

In the case of options (B) and (C),

Since the slopes of both graphs are not constant throughout, they do not represent uniform motion.

In the case of option (D),

The slope of the graph is zero, and it implies that the body is at rest.

Hence, option (A) is the correct answer.
