Typical Student Answers

How long would the ball bounce? (if you could measure the tiniest micro-bounces)

• Forever.
• Never stops.
• Counting all the bounces, it would bounce for all time.
• I guess it keeps bouncing.
• Looked to me like it bounced seven seconds!

These quotes are genuine impromptu answers by our students. A non-student said something like: "if it bounces an infinite amount of times, it must bounce an infinite amount of time."
