Now, my textbook says that force of friction is independant from the area of contact. But, when the tyres of my bicycle get deflated i have to exert extra force than otherwise. Why?
Yes, friction is affected by the surface area of contact. The larger the surface area of contact, the greater the friction between the two surfaces.
The surface area of contact affects friction by increasing the amount of microscopic bumps and irregularities that come into contact with each other. This creates more resistance and increases the friction between the surfaces.
Yes, there is a direct relationship between friction and surface area of contact. As the surface area of contact increases, the friction also increases.
No, friction cannot occur without any surface area of contact. Friction is the force that opposes motion between two surfaces in contact with each other.
The type of surface can affect the relationship between friction and surface area of contact. For example, a rough surface may have a higher friction with a smaller surface area, while a smooth surface may have a lower friction with a larger surface area.
