is b/c the lubricant:
a) reduces the normal force
b) changes the composition and qualities of the surfaces in contact
c) increases static friction
d) produces greater adhesion between the two surfaces
A lubricant decreases kinetic friction between surfaces. The most likely reason it reduces kinetic friction?
b. is the most correct choice. The purpose of lubircants is to reduce the moleuclar adhesion between the molecules where the two surfaces are in contact. It does this by changing the local characteristics of the two surfaces.
