Question

Which two surfaces would have the highest coefficient of friction?

Answer 1

Rough surfaces have the highest coefficient of friction due to increased points of contact.

Step-by-step explanation:

The two surfaces that would have the highest coefficient of friction are typically rough surfaces. When two rough surfaces are in contact, there are more points of contact between them, resulting in a higher coefficient of friction. For example, consider two rough pieces of sandpaper rubbing against each other. The rough texture increases the friction between the surfaces, causing a higher coefficient of friction compared to smoother surfaces.

Furthermore, adhesion between surface molecules contributes significantly to the coefficient of friction. Thus, two surfaces that have a high level of adhesion, such as rubber on asphalt, would exhibit a higher coefficient of friction compared to those with less adhesion, like leather on wood.

Answer 2

1. sandpaper against wood.
2. rubber mat against the floor of the shower stall.

# High coefficient of friction describes the degree of interaction between two surfaces. . A higher coefficient of friction indicates that two surfaces in contact have a greater resistance.
