What force opposes motion in fluids?
Viscous force
Reynolds number in terms of inertial force and viscous force?
Reynolds number is the ratio of inertia force to the viscous force. Reynolds number is used to find out the flow whether it is laminar or turbulent.
Which friction force is exerted by the fluids?
Viscous force. This is the frictional force between layers in relative motion
What two main forces act of a marble while it is falling through oil?
Buoyant force viscous force
What force is caused by friction between the air and the surface of an object?
The force is friction.In aerodynamics the frictional force of air resistance is commonly called "drag".Drag.Those are viscous forces.
What force opposes motion in fluids?
Viscous force
Why is it harder to move through a vicous liquid?
the viscous force is directly proportional to the viscosity of the fluid. so the more viscous a liquid is, more the viscous force and harder it is to move for a bod through it.
Reynolds number in terms of inertial force and viscous force?
Reynolds number is the ratio of inertia force to the viscous force. Reynolds number is used to find out the flow whether it is laminar or turbulent.
Force that resits motion?
Force that resists motion is frictional force, viscous drag
Is viscous force present in air?
yes, viscous force is present in air. it is proportional to the velocity and area of the body and acts in the opposite direction of velocity.
Which friction force is exerted by the fluids?
Viscous force. This is the frictional force between layers in relative motion
Can you give me the definition with examples of viscous drag force?

What is a fluid force that opposes motion?
It is known as viscous drag
Is viscous force directly proportional to surface area?
Yes
What is viscous flux?
Viscous flux usually refers to laminar flow. In most contexts, it refers to something like creeping flow or Poiseuille flow. Viscous flus usually arises from an external body force acting on a fluid. The external body force is usually pressure, or in some instances, centripetal force or magnetism.
What is the name of the frictional force between the surface and the air?
Viscous drag
What force in fluids oppeses motion?
Viscous force This is nothing but the frictional force between the adjacent layes of fluid in relative motion.
