Question

The position-time graph of a body is a straight line parallel to the X-axis. What does this imply?

• A. The body is at rest.
• B. The body is in uniform motion.
• C. The body is in non-uniform motion.
• D. The body is in periodic motion.

Answer 1

The correct option is A The body is at rest.

In a position-time graph, the X-axis indicates time and the Y-axis indicates the position.
If the graph is a straight line parallel to the X-axis, it means that the position of the body is the same at different intervals of time.
This can happen only when the body is at rest.
