Flash - Motion Tweening

• Creating a movie frame by frame would be very time consuming

• It would also be very jerky unless you were to draw each frame of the bouncing ball in a slightly different position sort of like going from top to bottom in baby steps.

• Flash will do this for you automatically

• First lets start a new file and draw a blue ball just like we did last lesson
