Most people think friction is what happens when two things are rubbed together. But there's so much more! Friction is a force that resists motion. Yet, without friction, motion would be impossible. Students will learn more about this natural force and the attempts made at controlling it in the world. Includes a hands-on activity and graphic…

Walking on a balance beam or riding a bike both require motion and balance. This program will reveal how unbalanced forces create motion, while balanced forces keep things still. Students also learn how concepts like velocity, acceleration, and momentum fit into this puzzle. A unique hands-on activity combined with vivid imagery and graphics…

Motion allows things to get done, to communicate and to travel. But is motion controlled? Students will learn about the universal laws that apply to motion, the forces that cause it and how it is related to balance. They will also discover why motion occurs when forces are out of control and learn more about this interesting concept by viewing…

This 15-minute VHS videotape introduces an interdisciplinary math, science, and language arts project for eighth grade. Students learn about and apply laws of motion, linear functions, and technical reporting as they design and present an ultimate roller coaster. The project is organized in five phases that generate knowledge about design…

Proposes the V-Scope as a teaching aid to measure, analyze, and display three-dimensional multibody motion. Describes experiment setup considerations, how measurements are calculated, graphic representation capabilities, and modes of operation of this microcomputer-based system. (MDH)
