On a flat surface, the coefficient of friction is a ratio between

the force of friction and the weight of the object.

Explanation:

The coefficient of friction (COF), is a scalar value without dimensions. It can be described as the ratio of the force of friction between two bodies and the force that presses them together. The force of friction will act against the direction of motion.

The coefficient of friction is highly dependent on the materials that are being used. Near zero to greater than one is range of The coefficient of friction. For those surfaces at rest and relative to each other COF is called as the coefficient of static friction.

answer; i believe that the correct answer is (lung);
