Projectile
Intended for use in my AP Calculus BC class.
Drag sliders at left to set initial conditions for the projectile scenario. The unlabeled green slider causes the projectile to travel through its trajectory, from launch until impact with ground.
On some devices with a keyboard, it may be easier to select the slider and then use the arrow keys to nudge the values up or down.
Display is admittedly messy, but you should be able to drag objects around to resolve overlap/clutter.
