Motion in two dimensions

Motion in two dimensions
Publication Date: September, 2007
Type of Resource: Interactive/Simulation

This downloadable resource is a simulation that illustrates velocity and acceleration vectors as changing arrows as a ball is moved around a screen.

Linear motion, simple harmonic motion and circular motion are demonstrated. The velocity and acceleration arrows can be shown together, or one hidden, or both can be hidden to allow students to predict their directions.

The simulation is good for investigating the difference between accelerated motion and constant speed motion as well as velocity and acceleration directions during circular motion. It is also good for investigating accelerating and decelerating motion.

Additional Information

This simulation is accessible with a standard web browser as long as Flash and Java are installed on your local machine, however, you may require assistance or permission from your local IT support person to install this piece of software.

Teacher tips can be downloaded once you become a registered user. 

Use is free although a donation is suggested.
