This web-based graphing activity explores the similarities and differences between Velocity vs. Time and Position vs. Time graphs. It interactively accepts user inputs in creating "prediction graphs", then provides real-time animations of the process being analyzed. Learners will annotate graphs to explain changes in motion, respond to question sets, and analyze why the two types of graphs appear as they do. It is appropriate for secondary physical science courses, and may also be used for remediation in preparatory high school physics courses. Resource includes interactive activity, lesson plan, and assessment with answer key. Note: Users must register to access full functionality of all the tools available with SmartGraphs, which includes authoring tools for customizing SmartGraph content.

SmartGraphs were developed by the Concord Consortium, a nonprofit organization dedicated to transforming education through technology.

The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion. (6-8)

2. The Nature of Mathematics

2A. Patterns and Relationships

6-8: 2A/M2. Logical connections can be found between different parts of mathematics.

9-12: 2A/H1. Mathematics is the study of quantities and shapes, the patterns and relationships between quantities or shapes, and operations on either quantities or shapes. Some of these relationships involve natural phenomena, while others deal with abstractions not tied to the physical world.

4. The Physical Setting

4F. Motion

6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.

9. The Mathematical World

9B. Symbolic Relationships

3-5: 9B/E2. Tables and graphs can show how values of one quantity are related to values of another.

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.

11. Common Themes

11B. Models

6-8: 11B/M2. Mathematical models can be displayed on a computer and then modified to see what happens.

6-8: 11B/M4. Simulations are often useful in modeling events and processes.

This cost-free article describes results of research in Grades 4, 6, and 8 on student understanding of motion. Findings suggest that students as young as Grade 6 can, with instruction, change entrenched incorrect concepts to construct accurate ideas about force and motion.

This is a microcomputer-based motion lab developed for cooperative learning groups. Students collaborate to predict shape of motion graphs, then analyze their own misconceptions.
