Curated OER
Surface Friction and Wear Characteristics of Common Materials
Students identify the factors affecting friction. In this physics lesson, students construct their own rocket car and race them. They graph the average speeds and discuss how lubricants affect friction between rubbing surfaces.

A Focus on Mechanical Friction
High schoolers explore mechanical friction. They perform experiments to observe the direction of mechanical motion and the difference between rolling and sliding friction. Data results on the experiments are recorded and students...
