Which of the following scenarios would create the most friction between the two surfaces? one choice answer.
A.
a shoe with a rubber sole moving against a smooth tile floor
B.
a shoe with a wooden sole moving against a smooth tile floor
C.
a shoe with a rubber sole moving against a ridged concrete driveway
D.
a shoe with a wooden sole moving against a ridged concrete driveway
Which do you think? Why do your shoes usually have rubber soles? Do you slip more easily on smooth tile or rough concrete?
To determine which scenario would create the most friction between the two surfaces, we need to consider the materials involved and the roughness of the surfaces.
Friction is defined as the resistance encountered when one object moves along or against another object. It is influenced by factors such as the type of materials and their roughness. Generally, rougher surfaces create more friction than smoother surfaces.
Let's evaluate the options:
A. A shoe with a rubber sole moving against a smooth tile floor: In this scenario, both the shoe sole and the tile floor are relatively smooth. Rubber has reasonably good grip, but the smoothness of the tile floor will reduce the overall friction.
B. A shoe with a wooden sole moving against a smooth tile floor: Wood has less grip compared to rubber, and the smooth tile floor will further reduce the friction. The wooden surface of the shoe sole will not provide much traction on the smooth tile.
C. A shoe with a rubber sole moving against a ridged concrete driveway: The rubber sole of the shoe will provide good grip, and the ridged concrete driveway surface will increase the overall friction. The roughness of the concrete will create more points of contact, resulting in increased friction.
D. A shoe with a wooden sole moving against a ridged concrete driveway: Wood has less grip compared to rubber, and the ridged concrete driveway will increase friction. Although the wooden sole may have fewer points of contact on the ridged surface compared to rubber, the increased friction due to the roughness of the concrete will still make it more challenging to slide the shoe.
Based on the evaluation, option C, a shoe with a rubber sole moving against a ridged concrete driveway, would create the most friction between the two surfaces.
