momentum (mechanics)

Explores how applied physics relates to the design and construction of roller coasters. Describes the physical dynamics of a roller coaster, explaining the role of potential and kinetic energy, friction, gravity, momentum and acceleration. Also introduces how the inertial effects, known as G forces, give roller coaster riders a thrilling experience.

Explains the concepts of motion and balance, looks at the connection between them, and discusses the related topics of gravity, friction, momentum, and equal and opposite reaction.

"Provides readers with an engaging introduction to momentum. With colorful spreads, clear text, helpful diagrams, and a 'Science in Action' activity, this book offers an exciting look at physics in the real world."--Publisher.

Bill Nye the Science Guy answers questions about momentum, and conducts two experiments that demonstrate action and reaction, and show that air escaping from a balloon can move the balloon along a string.

Contains science projects with gravity and motion and includes how-to photos, easy instructions, and short explanations.
