Slope and area on motion graphs
What you will learn: the slope of a graph tells you one quantity, and the area under it tells you another. You will measure both.
Tool:
Keys: space = play/pause the time cursor, r = reset.
Slope tool
Drag points A and B on the graph, or use the sliders.
Area tool
Drag the two edges on the graph, or use the sliders.
above the axis = positive below = negative
Edit points
Drag the round points to change the graph. The first and last points can only move up and down. Two points at the same time make a sudden jump.
