Question

The distance-time graph for an object is shown below. Which one of the following statements holds true for this object?

(a) The object is moving with uniform speed

(b) The object is at rest.

(c) The object is having non-linear motion.

(d) The object is moving with non-uniform speed.

Answer 1

Correct option is (b) The object is at rest.

As the graph is parallel to time axis, therefore the object is rest because position remains unchanged.

If the object is moving with uniform speed, then the graph is given by

If the object is moving with non-linear motion, then the graph is given by

If the object is moving with non-uniform motion, then the graph may be given by
