This project illustrates a fun use of the random tile.

In this project, three different types of acceleration are modeled.

This is a simulation of a simple spring. One of its end points is attached to a moving platform.

Creating a game with physics is a great way to learn them. In the classic Lunar Lander game, you can control the output of the rocket's motor so that the rocket ship touches the ground gently.

This project shows some ways to analyze the ball drop experiment.

This project shows some techniques for making a movie. See the "Make a Movie" project for the basics.

Etoys can accept input from a camera. It creates a series of still pictures (JPGs) from the movie.

This project shows a multi-frame animation.

This is a simulation of a salmon that tries to swim upstream of the river where it was born.

After making the "Follow the Road", the challenge is now to make the car drive down the middle of the road.
