friction

A detailed exploration of the science behind fearsome forces, paired with fun and relevant experiments, will make even the most reluctant readers excited to pick up this book.

An introduction to forces that discusses pushes, pulls, motion, direction, speed, and friction, and provides everyday examples and instructions for an activity.

Simple language and humorous illustrations show how forces make things move, prevent them from starting to move, and stop them from moving.

Describes the science behind race cars, discussing aerodynamics, velocity, and fuel types.

How does a sailboat, a dog sled, a waterwheel, and a train move? Are they pushed or pulled?.

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.

This episode features eleven music video parodies from the science guy's television series. The music videos cover different areas of science and are interspersed with facts and experiments presented by Bill Nye. Topics include velocity, friction, the water cycle, weather, brain function, methods of communication, oceanography, and recycling.
