What causes friction between fluids and how does it affect the flow of the fluids?
Friction between fluids is caused by the interaction of molecules within the fluid. This friction can slow down the flow of the fluids, making it more difficult for them to move smoothly. It can also create turbulence and resistance, which can further impede the flow of the fluids.

What are the main differences between viscosity and friction?
Viscosity is a measure of a fluid's resistance to flow, while friction is the resistance encountered when two surfaces move against each other. Viscosity depends on the internal friction within a fluid, while friction is a force that opposes motion between surfaces. Viscosity is specific to fluids, while friction can occur in both solids and fluids.
The friction between moving molecules in a liquid is called?
The friction between moving molecules in a liquid is called viscosity. Viscosity is a measure of a fluid's resistance to flow, with higher viscosity fluids being more resistant to flow than lower viscosity fluids.
Which friction force is exerted by the fluids?
The friction force exerted by fluids is typically referred to as viscous drag. This force arises due to the friction between the moving object and the fluid it is moving through. Viscous drag depends on the velocity of the object and the properties of the fluid.
Does Pascal's law apply to viscous fluids?
No, Pascal's law applies to non-viscous (incompressible) fluids. Viscous fluids have internal friction that causes them to resist flow and deform. This results in a different behavior compared to non-viscous fluids governed by Pascal's law.
What is the difference between drag and friction?
Drag is a force that resists an object's motion through a fluid (such as air or water), while friction is the force that resists an object's motion when in contact with a surface. Drag occurs in fluids, while friction occurs between solid surfaces.
What is the value of the friction coefficient between water and air?
Air and friction both being fluids, the resistive forces between them are more related to drag than friction.
What causes a boundary layer to develop in fluids?
A boundary layer develops in fluids due to the friction between the fluid and a solid surface. This friction slows down the fluid velocity near the surface, leading to the formation of a boundary layer where the flow transitions from the no-slip condition at the surface to a freer-flowing condition away from it.

Do fluids have friction?
Fluids have Friction. Everything in it, is under the force of fluid friction or drag. For example, a boat stops itself when the rowing stops, etc. Adarsh Kumar Dash
What causes creaking joints in arthritis?
The sinovial fluids and cartilage between normal healthy joints keep them moving freely and without pain. Arthritis is a situation where the cartilage which keeps the joint moving smoothly is destroyed or worn away. When this happens it is bone on bone and the friction causes creaking.
What is the difference between drag and friction?
Drag is a force that resists an object's motion through a fluid (such as air or water), while friction is the force that resists an object's motion when in contact with a surface. Drag occurs in fluids, while friction occurs between solid surfaces.
viscosity?
A property of fluids that causes them to resist flowing as a result of internal friction from the fluid’s molecules moving against each other.
What are the causes of fluid friction?
Fluids can be air or liquids when referring to fluid friction. A paper airplane flying through air is acted on my by friction of the atmosphere. A submarine or ship moving below or above the sea is affected by the fluid friction of water. This because matter rubbing against matter cannot do so without resistance from friction.
What is different between static friction and kinetic friction?
Between any two body surfaces in contact there acts an frictional force. A friction can operate between a given pair of solids, between a solid and fluid or between a pair of fluids. There are two types of frictional forces : kinetic and static friction. When two bodies in contact move with respect to each other , rubbing the surfaces in contact the friction between them is called kinetic friction. The directions of frictional forces are such that it opposes the relative motion. Friction forces can also act between two bodies which are in contact but not moving or sliding with respect to each other. The friction in such case is static friction.
