Description

Our four-sided friction block demonstrates how frictional characteristics affect the force required to move a stationary body. Offering four different friction surfaces, 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) to all four sides.

Material: sandpaper, vinyl, paper (Cellulose), wood (Steam Beech).

Dimensions: 2” x 2” x 2”
