This simulation gives students a chance to practice two-dimensional vector addition in an interactive format with immediate feedback. The magnitude and direction of two vectors are given; the students' task is to determine x and y components, length of the two vectors, and the resultant sum. Users may select "Check Answers" to find out if their response is correct, or select "Show Answers" to see the correct values displayed.

SEE ANNOTATIONS (below) for a tutorial on the topic of vector fundamentals, 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
• 6-8: 11B/M2. Mathematical models can be displayed on a computer and then modified to see what happens.
• 9-12: 11B/H2. Computers have greatly improved the power and use of mathematical models by performing computations that are very long, very complicated, or repetitive. Therefore, computers can reveal the consequences of applying complex rules or of changing the rules. The graphic capabilities of computers make them useful in the design and simulated testing of devices and structures and in the simulation of complicated processes.
the Physics Classroom: Vector Addition (Author: Tom Henderson)
Date: 06/09/2010

An editor-recommended tutorial to accompany the "Vector Addition Model". It begins with very simple concept-building, then moves into detailed explanations of the math involved to determine the magnitude of a vector (both the trigonometric and the parallelogram methods).
