Vector Components Model

written by
Andrew Duffy

This computer model allows students to split a vector into its components and practice finding the magnitude and direction. In addition, it offers a "Find components" mode, where magnitude and direction of the vector are given and the student's task is to find the x-component and the y-component of the vector. After entering calculated values, users can check their answers with one click.

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).

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.

Editor-recommended tutorial to accompany the Easy Java Simulation "Vector Components Model". It begins with concept-building through use of varied examples, then moves into a detailed explanation of the math involved to determine the magnitude of a vector.
