Unfinished project. Well, technically, it's just an animation. Not enough frames yet, technically, I have enough for the work, but yeah. The ball falls and stops in mid air. Click on the green flag to watch what I have so far. Slide the Frames Per Second slider to change the speed of the animation. The bottom Variable where it says "YOUR DEVICE FRAMES PER SECOND" is basically how fast your device is running on this project. Classwork: Animation Using Costumes.
