Question

The figure shows a graph of velocity versus time for a moving object. Which description matches the graph?

Answer 1

It's a decreasing line, so we can say this object is going slow in a constant velocity.

Answer 2

The description which matches the graph is:

• The object is slowing down.

Explanation:

We are given a graph which represents the velocity of a moving object with respect to time.

The graph is a line which is decreasing continuously with the increasing time.

This means that the object is slowing down with the increasing time.

Also, we know that:

If the graph is a line then the slope is always constant.

This means that the acceleration is constant.

( since the ratio of change in velocity to change in time is the acceleration of the object which is the slope of the graph)
