This is an interactive simulation created to help beginners differentiate velocity and acceleration vectors.  The user can move a ball with the mouse or let the simulation move the ball in four modes of motion (two types of linear, simple harmonic, and circular). Two vectors are displayed -- one green and one blue. As the motion of the ball changes, the vectors also change. Which color represents velocity and which acceleration?

This item is part of a larger and growing collection of resources developed by the Physics Education Technology project (PhET), each designed to implement principles of physics education research.

Please note that this resource requires Java Applet Plug-in.
Editor's Note: This simulation was designed with improvements based on research of student interaction with the PhET resource "Ladybug Revolution". The authors added two new features for the beginning learner:  linear acceleration and harmonic motion. To supplement the simulation, we recommend the Physics Classroom tutorial "Vectors and Direction" and the teacher-created lesson, "Vectors Phet Lab" -- see links in Related Materials.

4. The Physical Setting

4F. Motion
  • 3-5: 4F/E1a. Changes in speed or direction of motion are caused by forces.
  • 6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.

11. Common Themes

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

The Physics Classroom: Vectors and Direction (Author: Tom Henderson)
Date: 09/17/2012

As instructors, we may forget that certain representations (like vector arrows) seem like a foreign language to beginning students. This thoughtfully-crafted tutorial introduces vector diagrams in kid-friendly language and extends the learning to interactive practice problems with answers provided.

This resource is part of a Physics Front Topical Unit.


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

This very simple simulation can help beginners understand what vector arrows represent. It was designed by the PhET team to target specific areas of difficulty in student understanding of vectors. Learners can move a ball with the mouse or let the simulation control the ball in four modes of motion (two types of linear, simple harmonic, and circular). Two vectors are displayed -- one green and one blue. Which color represents velocity and which acceleration?
