Bouncy Ball Animation

In class for the past week we was doing some animations on a site called Adobe Flash CS5 which was moving animation with objects, like i did with my last Adobe Flash CS5 animation of the square turning into a circle but this time i chose to do a bouncy ball, bouncing from one way to the other. I enjoyed doing this practise of moving animation but it took me ages to work out how to do it and after i was really pleased with it and it helped towards my final animation and how i would want to present it.
