Yes, in general, an increase in surface area and pressure can lead to an increase in friction between two surfaces. This is because a larger surface area and higher pressure result in more points of contact between the surfaces, which can generate greater frictional forces.

How does low air pressure in bicycle tires reduce the efficiency of a bicycle?

Flabby tyres produce more friction with the road.Less air pressure creates more surface friction, the less surface friction there is the better. (Example look at the very skinny narrow tyres on road racers as they don't need a lot of surface friction while mountain bikes have thick tyres as they need more friction)


How is static friction and kinetic friction differ from each other?

Static friction occurs when an object is at rest on a surface, preventing it from moving. Kinetic friction occurs when an object is already in motion on a surface, resisting its motion. Static friction is usually stronger than kinetic friction.


How pressure depends on force and area?

Pressure = force/area This means that the larger the force, the larger the pressure. But the smaller the area, the larger the pressure.


Why does an object take longer to slow down on a slippery surface?

On a slippery surface, there is less friction between the object and the surface, which reduces the force acting against the object's motion. This means that it takes longer for the object to decelerate and come to a stop compared to a surface with more friction.


Is friction independent of the area of contact?

Generally no. The friction force is typically assumed independent of surface area, and proportional to the force between the two objects. By changing the contact area, you are changing how that force is concentrated. i.e. a small surface area means that your force is distributed across a small region, creating a high pressure (force/area) at the contact. By increasing the surface area, you distrubte that force and lower the pressure. This is, however, an idealization and can break down in some instances.


Does the nature in contact influence friction force?

Since friction means a contact force, the nature of contact will influence friction force. Smoothness of objects affect the friction force. However, as contact pressure rises, the friction does not rise.


Why does water pressure increase with surface area and fluid density?

Water pressure increases with surface area because a larger surface area means the force is distributed over a greater area, resulting in higher pressure. Fluid density also affects water pressure because denser fluids have more mass per unit volume, increasing the pressure at a given depth due to the weight of the fluid above.


What is the relation between pressure and surface area?

Pressure is inversely proportional to surface area. This means that as surface area decreases, pressure increases and vice versa, given a constant force. This relationship is described by the equation: Pressure = Force / Area.


Is Traction affected by friction?

Yes, traction is affected by friction. Friction between a surface and an object can either increase or decrease the traction, depending on the circumstances. More friction typically means better traction, while less friction can lead to reduced traction.


How does the friction between the ground and molecules in the air affect wind?

Friction between the ground and air molecules can create drag, slowing down the movement of air near the surface. This drag can influence the speed and direction of wind flow, particularly at lower levels of the atmosphere where the friction is most significant.


Does clay have more friction than sandpaper?

Yes, clay does have more friction than sandpaper. This is because, clay is a much heavier object/material then sandpaper, therefore if you were to drag a lump of clay on the floor and measured the friction, it would be higher then the amount of friction caused by sandpaper. If the amount of force needed to pull the clay is larger then the amount of force needed to pull the sandpaper, that means that there is a much larger amount of friction present, because the more friction there is present, the harder you would need to pull. Hope this helps.


What is the effect of the elasticity of the arterie on arterial blood?

The elasticity enables the arteries to change their diameter. Smaller means more pressure, larger means lower pressure.
