Graphs plotted

Graphing displacement

You can show the progress along a track on a pair of graphs. One graph for how far up or down, one graph for how far right or left. Both from a particular point of view. A single displacement arrow tells you both the up-down distance and left-right distance.

Graphing speeds

Or you could choose to make a graph of the speeds – One graph for up or down, one graph for right or left. A velocity arrow tells you about both speeds at once. That’s the magic of arrows.

Both displacement and velocity

You could plot speeds and distances at once.

Arrows are more straightforward, both as a record of what happened and as a tool to predict what will happen.
