According to our kinematic equation, distance should be proportional to time squared. Let's make another graph. First ... Here is a force diagram for a cart (with no friction) rolling down ...

The steeper the line, the greater the increase in speed. The area under the graph = the distance travelled. This is a speed-time graph for a car moving between two sets of traffic lights.

A sloping line on a distance-time graph shows that the object is moving. See how much you know about distance-time graphs by answering the questions below. The total distance travelled by the ...
