# Can you help me interpret the motion of the following position-time graph?

##

I want to interpret the motion of each slope in this p-t graph. For example, considering that the position is in (m) [N], I would say that the first slope represents an object moving [N] at a constant velocity. But, how would I interpret slopes that go are situated **below the x-axis**?

As we see in the given graph, there are eight time segments

1.

We see that slope of the line is given by

Implies that the object is moving in the positive direction with a constant velocity of

2.

We see that slope of the line is given by

Implies that the object is moving in the positive direction with a constant velocity of

3.

We see that slope of the line is given by

Implies that the object is stationary

4.

We see that slope of the line is given by

Implies that the object is moving in the negative direction with a constant velocity of

5.

We see that slope of the line is same as in step 3.

The object is stationary.

6.

We see that slope of the line is given by

Implies that the object is moving in the positive direction with a constant velocity of

7.

We see that slope of the line is given by

Implies that the object is moving in the positive direction with a constant velocity of

8.

We see that slope of the line is same as in steps 3 and 5.

The object is stationary.
