friction

Presents simple hands-on experiments that demonstrate the properties that make sliding easier or more difficult.

Text and photographs provide information for young readers about the scientific concepts of force, gravity, and friction.

Introduces students in grades five through eight to key concepts in physics, focusing on friction, using visuals and experiments to discuss sliding, rolling, and fluid friction, lubricants, friction measurement, wind resistance, static friction, and friction use. Includes review segments.

Dorothy Ann loves her physics book; Ralphie loves baseball. Ms. Frizzle ingeniously combines the two in a page-hopping adventure through Dorothy Ann's book to a "Frictionless baseball game." The whole class learns about pushes and pulls in a remarkable day at a thoroughly unique ball game.

Explains what friction is, the rules of friction, how friction can be reduced and more.

Bill Nye the Science Guy answers questions about friction, and leads an activity to design an object that will hover over a flat surface on a cushion of air.

An overview of forces and gravity, covering how these things shape and control everything in the universe as well as topics such as friction and magnetism.

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

Photographs and simple text describe how friction works such as how friction keeps different things from slipping or sliding.
