Forces and Motion

How can a Distance - Time Graph
be used to show the Motion of an Object?

You may be shown a graph like the one below
and be asked to describe the motion of the object.

In region A the object is moving with constant velocity.

In region B the object is at rest (not moving).

In region C the object is again moving with a constant velocity
but compared with region A
1. the object is moving more slowly because the slope is less steep
2. the object is moving in the opposite direction
because distance is decreasing as time goes by.

Compare this with the velocity - time on page 11.
