Graph Matching Motion Model
written by Andrew Duffy
This simulation gives students a powerful way to investigate the meaning of shape and slope for three types of motion graphs: position vs. time, velocity vs. time, and acceleration vs. time. The simulation starts with a motion diagram of a blue ball moving horizontally, with a position vs. time graph simultaneously displayed. The student's task is to "match" the motion of an adjacent red ball to that of the blue ball, by using sliders to set the initial position, initial velocity, and acceleration. To set it up correctly requires the student to analyze and interpret motion of the blue ball. After matching the motion, students can predict what the velocity and acceleration graphs look like by sliding the end points of the red lines up or down to give correct straight-line graphs.

See Annotations Below for an editor-recommended interactive tutorial on interpreting motion graphs.

• 6-8: 9B/M3. Graphs can show a variety of possible relationships between two variables. As one variable increases uniformly, the other may do one of the following: increase or decrease steadily, increase or decrease faster and faster, get closer and closer to some limiting value, reach some intermediate maximum or minimum, alternately increase and decrease, increase or decrease in steps, or do something different from any of these.
• 9-12: 9B/H4. Tables, graphs, and symbols are alternative ways of representing data and relationships that can be translated from one to another.
The Physics Classroom: Describing Motion with Graphs (Editor: Caroline Hall)
Date: 06/14/2010

This editor-recommended interactive tutorial from The Physics Classroom will help students understand shape and slope in motion graphs. It discusses the topic in an easy-to-understand language which is supported by a wealth of graphics and a question-and-answer set.

This resource is part of a Physics Front Topical Unit.

Topic: Kinematics: The Physics of Motion
Unit Title: Modeling Motion

This simulation is a powerful way to investigate the meaning of shape/slope for 3 types of motion graphs: p-t, v-t, and a-t. Students "match" the motion of a ball whose movement is automatically generated. To do it correctly requires analysis of the motion. Next, learners predict what the graphs will look like by using sliders to generate their own straight-line graphs.
