While drilling metal, ben poured oil over the area, which best explains why he did this ?
a. reduce fluid friction
b. reduce kinetic friction
c. increase fluid friction
d. increase kinetic friction pls you all so much : )

Answer;

B. Reduce Kinetic friction

Explanation;

-Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

-Kinetic friction is a force that acts between moving surfaces. An object that is being moved over a surface will experience a force in the opposite direction as its movement. The magnitude of the force depends on the coefficient of kinetic friction between the two kinds of material.
