Basics of a Bouncing Animation
Flash Animation 14: Gravity, Squash, and Stretch
Now I need to create a motion tween to show the first completed bounce cycle. It's just a simple arc; for web animation, we can leave it as a three-point triangle, as it will be moving too quickly to really reflect the difference and so there's no need to create extra keyframes to define the arc shape.

All you need are the basics: a keyframe at the point of liftoff, a keyframe at the peak of the bounce arc, and a keyframe at the point of landing, with motion tweens between each one. However: Do not make the snowball into a symbol before you create the tween. When you insert the motion tween it will make symbols of them on its own, but rather than library symbols with specific instances, they'll be an internal part of the tween. This is essential later.
