Prediction
One way to graph motion is to plot "position" as it changes over time. Position is
the distance of a location measured from a definite reference point. The reference point
could be any location that we choose, but once we choose it, it is fixed. We will call this reference point position 0
and give it the special name of “origin.”
Now, try drawing a graph that you think predicts how Vijay's position changes over time. Draw a line on
the graph below that you think describes his trip. Click on the pencil tool at the
right to draw your prediction line.
Here is what you need to know to get started:
• The Library is located at the origin, position 0.
• The distance between the Library and Cinema is 7400 meters.
• Vijay travels from the Library to the Cinema and back to the Library.
After you have drawn your prediction, use the
label tool (just below the pencil tool) to mark the positions of the
Library and the Cinema on the graph.
