Bouncing Ball Tests

Here are my bouncing tennis ball (top) and bowling ball (bottom) tests.  I think they turned out pretty well.  I made several versions of this, and this is a redo that I handed in for class.  This was the first assignment.  I was really nervous handing this in, but all in all, I think I got the basic animation principles down in this.  Let me know what you think!!  And thank you for looking!! :)
