Building upon their understanding of forces and Newton's laws of motion, students learn about the force of friction, specifically with respect to cars. They explore the friction between tires and the road to learn how it affects the movement of cars while driving. In an associated literacy activity, students explore the theme of conflict in literature, and the difference between internal and external conflict, and various types of conflicts. Stories are used to discuss methods of managing and resolving conflict and interpersonal friction.

Engineers use their understanding of the force of friction to design safe roads, tires, cars and brakes. Transportation and automotive engineers make sure that roads and tires provide the right amount of friction because friction provides traction and control for a safe driving experience, especially in icy or wet conditions. Even designing how paper is moved through a copy machine involves an understanding of friction. Engineers also reduce the force of friction between moving mechanical parts (in engines, tools, artificial limbs, etc.) so the parts run smoother and last longer. Explain how friction relates to the movement of cars (moving forward, stopping, turning corners). Understand that friction is a force that arises when things rub together Predict ways to improve the movement of cars in snow and ice, and explain why Understand why engineers must understand frictional forces, especially when designing automobiles 50TeachEngineering.orgSabre DurenBen HeavnerMalinda Schaefer ZarskeDenise CarlsonGittewitt, Paul.
