Teach Engineering: Does Contact Area Matter?
Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if the amount of area over which an object contacts a surface it is moving...
TeachEngineering
Teach Engineering: Sliders (For High School)
In this hands-on activity, students learn about two types of friction - static and kinetic - and the equation that governs them. They also measure the coefficient of static friction and the coefficient of kinetic friction experimentally.
