Why Do Balls Bounce?
By Rob Moore
Review by Mark
 
This book is about gravity.  Gravity is an invisible force.  Gravity keeps us from floating away.  Skydivers don’t fly away because of air resistance.  Gravity holds the moon in its orbit.  When you hit a fly ball it is a parabola.  A ball bounces because it dents.  I recommend this book to people who like sports.

  3. I don't really like sports, but I do find the subject of gravity interesting. I appreciate the way you gave specific examples to explain how gravity works. Great review.

  4. Mark, what is a parabola? Was there a glossary in the book to let you know? You did a great job connecting this book to those who like sports, not everyone realizes that sports and science are connected! Well done! :0), Mrs. Haas
