====== Coefficient Of Friction 1 ====== {{tag> needs_review untagged unlocated}} // // ===== Description ===== Demonstrate coefficients of friction of different materials Newton's First Law, Second Law, Friction ===== Purpose ===== 1. To demonstrate the "angle of friction" for a block and a surface. 2. To show that frictional force is independent of surface area. 3. To demonstrate the range of values of the coefficient of friction. ===== Apparatus ===== - Adjustable incline - Blocks (wooden, aluminum and teflon coated) ===== Setup ===== 1. Show that there is a minimum angle for slipping which does not depend on surface area. 2. Show variation in angles or speed for wooden block, aluminum block and block with teflon surface.
