The Car Race model is a Java-based simulation that will help students visualize the difference between constant velocity and constant acceleration. It features the classic physics scenario in kinematics: a lead car travels at constant velocity on a straight track, while a second car moves from rest with constant acceleration in the same direction. Each time the game is reset, the position and velocity of the lead car change, while the acceleration of the second car also changes. Which car will win?

SEE ANNOTATIONS (below) for an interactive tutorial on the topic of velocity and acceleration, recommended by The Physics Front editors.

This item was created with Easy Java Simulations (EJS), a modeling tool that allows users without formal programming experience to generate computer models and simulations. To run the simulation, simply click the Java Archive file below. To modify or customize the model, See Related Materials for detailed instructions on installing and running the EJS Modeling and Authoring Tool.

Please note that this resource requires at least version 1.5 of Java (JRE).

AAAS Benchmark Alignments (2008 Version)

11. Common Themes

11B. Models
  • 9-12: 11B/H3. The usefulness of a model can be tested by comparing its predictions to actual observations in the real world. But a close match does not necessarily mean that other models would not work equally well or better.

AAAS Benchmark Alignments (1993 Version)

4. THE PHYSICAL SETTING

F. Motion
  • 4F (3-5) #1.  Changes in speed or direction of motion are caused by forces. The greater the force is, the greater the change in motion will be. The more massive an object is, the less effect a given force will have.

11. COMMON THEMES

B. Models
  • 11B (9-12) #1.  The basic idea of mathematical modeling is to find a mathematical relationship that behaves in the same ways as the objects or processes under investigation. A mathematical model may give insight about how something really works or may fit observations very well without any intuitive meaning.
Recommended Supplementary Tutorial (Editor: Caroline Hall)
Date: 06/09/2010

The Physics Front editors recommend the following interactive tutorial on velocity and acceleration by Tom Henderson, author of The Physics Classroom collection. Using an engaging format with animations and interactive questions, the author helps students see how velocity is different from speed, what acceleration means, and how each can be represented in terms of an object's position vs. time.
