Friction Block

Description

Our four-sided friction block demonstrates how frictional characteristics affect the force required to move a stationary body. Offering four different friction surfaces (sandpaper, vinyl, paper, wood), the block can be used to teach numerous concepts involving friction, including force and energy, gravity, static friction, and kinetic friction. Comes with a hook on one side for towing and a threaded brass post allows for easy addition of slotted masses (sold separately) on all four sides.
