Motion in two dimensions
This downloadable resource is useful for demonstrating velocity and acceleration vectors.
The resource, which can be either displayed in a web browser or downloaded as a standalone Java application, 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 or both can be hidden to allow students to predict their directions.
