Friction Cube with Four Surfaces, For exploration into force of friction., Each

Details

The Friction Cube offers four surfaces for exploring the force of friction. Each side of the 2-inch cube provides a surface with a different coefficient of friction - wood, paper, vinyl, and sandpaper. By pulling the cube using the attached hook, you can both qualitatively and quantitatively demonstrate the properties of static and kinetic friction. An instruction manual is included.
