Description: A block is placed on an adjustable inclined plane which can be raised until the block slides down the plane.  The tangent of the angle can be used to determine the coefficient of friction between these surfaces.  Blocks with different surfaces, such as bare wood and sandpaper-covered wood, may be used.
