Viscous force
This is nothing but the frictional force between the adjacent layes of fluid in relative motion.
Viscosity is the force that opposes motion in fluids. It is a measure of a fluid's resistance to flow, and it arises due to internal friction between the molecules within the fluid.
Such force is called viscosity..the force produces in liquid and opposes the motion of fluid and also the motion of the objects in fluid..it is also called the internal friction..
Named as frictional force in case of solids and named as viscous force in case of fluids, ie liquids and gases.
For solids, force can cause deformation or change in shape, depending on the material properties. This deformation can be elastic (material returns to original state after force is removed) or plastic (permanent change in shape). In fluids, force can cause motion or flow; the behavior of fluids under force is described by the principles of fluid mechanics, which include properties such as viscosity and density.
The frictional force exerted by fluids is called drag force. This force acts opposite to the motion of an object as it moves through a fluid, such as air or water, and it can affect the speed and direction of the object.
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.
Friction is a force that resists the relative motion between two objects (which may be solids or fluids). Metaphorically, it is a situation in which actions by individuals can cause conflict between them.
Hydrodynamics means the branch of science that deals with the dynamics of fluids, especially incompressible fluids, in motion or the dynamics of fluids in motion. Hydrostatic in relation to fluids that are not moving in Room, Temperature, Pressure.
Force has size, which is how much force put into somethig, e.g., 10 Newtons of force. It has motion because force is basically motion, because force can be unbalanced or balanced, and unbalanced causes motion, and is basically motion.
FRICTION and inertia that force can have on motion
Force that resists motion is frictional force, viscous drag
When a force is acted on an object the motion changes. Newtons 2nd law of motion states: An object in motion will stay in motion, and an object out of motion will stay out of motion, unless met with an unbalanced force. If a force is aplied to an object in motion it either accelerates, or it will stop once met with sed unbalanced force.
