In the past, it seemed obvious that a heavier object would fall faster than a lighter one. It also appeared reasonable to believe that the earth was a stationary center to the planetary system. Of course, time and investigation proved both of these beliefs to be false. The work of scientists such as Galileo and Newton helped to reveal basic laws of motion that still are applicable. In this volume of the "Secrets of the Universe," readers are introduced to the work of scientists who studied various elements of motion.
