Q11 of 139 Page 39

What conclusion can you draw about the speed of a body from the following distance-time graph:

It shows the graph for an object moving at a constant velocity. You can see that the displacement is increasing as time goes on. The gradient, however, stays constant (remember: its the slope of a straight line), so the velocity is constant. Here the gradient is positive, so the object is moving in the direction defined as positive.
