Bouncing Around

The bouncing ball question from tonight's homework might be a little difficult to visualize. Watch this animation which shows the height of the ball bouncing and simultaneously draws the graph of it's height over time -- it'll help. We'll be talking about it in class on Monday.

Whew! Today was a tough class for me. Actually, the last few have been that way. I feel like I'm up there bouncing around the class, asking questions, trying to get everyone involved, and more often than not, it seems like the room is empty. You're all there in body but there seems to be a lack of spirit. What's up folks? Should I shower more often? ;-) Feel free to comment anonymously to this post if you like. It just seems to me that we've got a bit of a "disconnect" going on and I'd like to get past that.

BTW, can you tell if that ball is bouncing up? or down? Does it make any difference if you tilt your head 90 degrees to the left? ;-)
