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).

This item is comprised of a wheel with a center shaft, suspended at 2 ends by a chord and that can be wound manually to the top and released. The unwinding of the chord, as the wheel descends, changes potential energy to kinetic energy. Upon reaching the end, it reverses itself and as it winds back up again, changing kinetic energy back to potential energy. This is a continuous process; however, energy is lost due to friction that ultimately slows the wheel to a stop.
