This simulator allows you to fire cannonball projectiles, varying their launch parameters, air resistance and gravity, and observing resulting trajectories.

Based on "The Art of Renaissance Science: Galileo and Perspective," a videotape by Joseph W. Dauben, CUNY Graduate Center and Lehman College.

Examines Galileo's experiments with the inclined plane on a table, which were used to study projectile motion. Galileo correctly reasoned that projectile was subject to two independent motions, and these combine to provide a parabolic curve.
