FRICTION BLOCK SET

FRICTION BLOCK SET

• Students can study the effects of friction on a variety of surfaces and to distinguish between the coefficient of static and sliding friction.
• This Friction Block set has four blocks; two with a hook and eye for connecting together, another with a mirror on one surface and the third a mirror on one side and sandpaper on the other.

(Wikipedia excerpt: ..."...Sliding friction (also called kinetic friction) is a contact force that resists the sliding motion of two objects or an object and a surface. Sliding friction is almost always less than that of static friction; this is why it is easier to move an object once it starts moving rather than to get the object to begin moving from a rest position.

F k = μ k ⋅ N {\displaystyle F_{k}=\mu _{k}\cdot N}

Where Fk, is the force of kinetic friction. μk is the coefficient of kinetic friction, and N is the normal force....)
