Viscous drag in a liquid refers to the resistance force experienced by an object moving through the liquid due to the viscosity of the fluid. It is caused by the interaction between the moving object and the fluid molecules, which create a frictional force that opposes the motion of the object.
Force that resists motion is frictional force, viscous drag
It is known as viscous drag
Viscous drag
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.
If a fluid in laminar flow flows around an obstacle, it exerts a viscous drag on the obstacle. Frictional forces accelerate the fluid backward (against the direction of flow) and the obstacle forward (in the direction of flow). The viscous drag force increases linearly with the speed of the fluid.
Viscous drag is a type of drag force caused by the interaction between an object and the fluid it's moving through. It occurs when a fluid resists the motion of an object, resulting in a slowing or halt in its movement.
If an object is passing through a fluid or medium then faces retarding or opposing force this force is called Drag Force
Moving through a viscous liquid is harder because the liquid has higher resistance to flow due to its thickness and stickiness. This resistance causes a drag force that opposes the movement of objects through the liquid, requiring more force or energy to overcome.
The force of gravity pulls water downward, but surface tension and viscous drag can slow down its movement. Surface tension causes water molecules at the surface to stick together, creating a barrier. Viscous drag is the resistance to flow caused by the water's contact with surfaces or objects.
Force on moving object by air friction: velocity2 * objects drag coefficient > Force on stationary object by wind: wind speed2 * objects drag coefficient
In geneal frictional force. If it rubs against a surface then it is known to be friction. If it drags the moving body then it is said to be viscous drag.
