Question

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

• A. The body is not moving.
• B. The body is accelerating at a constant rate.
• C. The body is moving with constant velocity.
• D. The body is undergoing uniform circular motion.

Answer 1

The correct option is A

The body is not moving.

The slope of distance-time graph gives speed of the body.

$Speed=\frac{distancecovered}{timetaken}$
$=Slopeofdistance-timegraph$



Since the slope of the graph is zero, hence speed is equal to zero which means that the body is at rest.
