Projectile Motion
Press "Initialize" to make a ball appear, and "shoot" to, well, shoot it. Notice how the position of the ball along the horizontal axis and the vertical axis changes. In the vertical, the ball has uniformly accelerated motion, while in the horizontal, it has uniform motion. In this way, we can analyze a more complex 2-dimensional motion by breaking it down into separate 1-dimensional motions, which are easier to analyze.
