What can be calculated for a distance-time graph?

Answer 1

Here are some things that can be determined from a distance-time graph:

• Total distance travelled, at a particular time.
• Average velocity at a particular time (take the distance at that point and divide by the elapsed time).
• If you can determine the slope at a particular point, then you can determine instantaneous velocity.
• You can tell the direction that the object is travelling: away from the starting point (positive slope) or toward the starting point (negative slope).

If you can determine the second derivative of the graph, you can calculate the instantaneous acceleration as well.
