Java

This Java applet demonstrates projectile motion with no air resistance using various accelerations in the x and y directions.

The slider at the top controls the x acceleration. Pushing it all the way to the left sets a high negative acceleration. That is, a large acceleration to the left. Placing the slider in the middle makes the x acceleration zero. And sliding it to the right makes for larger and larger positive x accelerations.

The slider on the right works in a similar manner for the y accelerations. Go to the top of the slider for a large positive, or up, y acceleration, go to the bottom for a large negative y acceleration. Place the slider in the middle for zero y acceleration.
