Difference between dynamic and kinematic viscosity?
dynamic viscosity is the quantitative expression of fluid's resistance,while kinematic viscosity is the ratio of fluid viscous force to inertial force.
What force opposes motion in fluids?
Viscous force
What is the ratio of the net force exerted on an object and its acceleration?
inertial mass
Which friction force is exerted by the fluids?
Viscous force. This is the frictional force between layers in relative motion
Can you distinguish between real force and pseudo force?
Real forces have its origin in matter such as electricity,gravitation etc.Pseudo force is caused by inertial motion such as centrifugal force.
Difference between dynamic and kinematic viscosity?
dynamic viscosity is the quantitative expression of fluid's resistance,while kinematic viscosity is the ratio of fluid viscous force to inertial force.
How does mass affects the force?
Mass and Force have no relationship except the gravitational force that is dependent on the mass of the body. Mass affects only the inertial force. Inertial force is the force required to change a state of rest or motion of a body. Greater the mass greater the inertial force required.
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.
What is the ratio of the net force exerted on an object and its acceleration?
inertial mass
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 of the following are being investigated to contain fusion reactions on earth?
magnetic confinement inertial confinement
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
