This week freshmen Physical Science students measured static friction (the friction of the object resting on the surface) and the kinetic friction (when the object is moving over the surface) with different masses of objects over varying surface textures. Then students measured the force necessary to lift a block vertically and how that force is reduced when the object is lifted on an incline plane at three different angles. Before doing these activities, students learned all the various ways friction is part of our lives: gravel on icy roads, our fingerprints, the friction between our shoes and the ground…

Science in action!
