Demonstration Devices > FRICTION BLOCK, 4-SIDEDThe Four-Sided Friction Block makes learning about friction easy! Show how different frictional characteristics affect the force required to move a stationary body. The friction cube includes 4 different surfaces on a two inch wood cube. The friction cube comes with a hook on one side for towing against inclined panes and other surfaces. The Friction Cube can be used to teach numerous concepts involving friction, an inclined plane, work, and mathematical calculations. Four friction surfaces: Sandpaper, Vinyl, Paper, Wood. Size: 2” x 2” x 2”.
