Correcting Tangents:

The problem that were having with our scaling of the ball is a common problem that happens with a lot of key frame animation.

It's caused by the fact that the default tangent type is Smooth, which generates "best fit" curves between the keys.

For our Scaling, we want the curve to be Linear, meaning it interpolates directly from one key to the next.

Open Track View.

Expand the Sphere's tracks and select the Scale track:

Set the level to Edit Keys:

Right Click on the first Key in the Scale Track. This will bring up the Key Info Box.

Change the Tangent Type for all the Keys  to Linear. (If you don't know how to do this, see Lecture 6 Page 5.)

Now play your animation. You should have a bouncing ball!
