Internal friction of a molecular layer refers to the resistance encountered when molecules within that layer move or slide past each other. It can be due to interactions between molecules, such as van der Waals forces or hydrogen bonding, which impede their motion. This internal friction can affect properties like viscosity and flow behavior of the molecular layer.

Why does friction and gravity act on a soccer ball?
That question doesnt exactly make sense, but if you meant HOW does friction and gravity AFFECT a soccer ball, the friction of the grass and ball affects the speed, and the gravity pushes the ball down to the ground. Hope it helped! -Cara
What is meant by the sentence the hair dryer has double insulation?
The statement "the hair dryer has double insulation" means that the hair dryer is designed with an extra layer of insulation to protect against electric shocks. This additional layer provides an added safety measure by reducing the risk of electrical hazards.
What is meant by internal energy of the system?
Depending what you relate it to. In an electronic system it would relate to the amount of watts consumed or supplied; whereas, an organic system would be the magnitude of glucose (or equivalent).
Does oil work better then water in reducing friction between two surfaces?
Oil fills in the gaps (bumps on every surface at microscopic level) of machine parts to reduce friction, damage and heat. If there weren't any oil, the engine would only last minutes before it would melt down. The oil reduces friction but doesn't get rid of it completely....If this answer isn't very good, I'm sorry im just 12:)
What is the friction force if a crate is at rest on the surface and a horizontal force of 50N is applied to it?
For every action there is an equal and opposite reaction, so if you push on a crate, the crate pushes back with a normal force equal to the force exerted. Thus, expect a force of 50 N to push back at you. However, if you meant the normal force of the ground exerted on the box, then that would included the 50 N force and the weight of the crate.
What is meant by tribology?
It is the study of friction and wear
What is meant by the force of friction?
Friction is a force, which (usually) tends to slow moving things down.
What is meant by friction?
A resistance that acts when an object moves.
Does brakes on a bicycle have a lot of friction or not much and is it useful or not useful?
Brakes are meant to have a lot of friction and it's useful.
What is friction and what is meant by maximum friction?
Friction is a force that opposes motion. Maximum friction is the?æ force that must be overcome in order for a body to start moving.?æ Maximum friction is equal to the?æ product of normal force and coefficient of the friction.
What is meant by the internal intonation of a wind instrument?
intonation
What is meant by the hole int the ozone layer?
The thinning of ozone layer is ozone hole. It is caused by ODS.
Why does friction reduce the mechanical advantage in machines?
Because some energy is expended in overcoming the friction and not applied to performing the task which the machine is meant to do.
What is meant by the term the depletionn of the ozone layer?
Depletion is the thinning of ozone layer. It is due to man made CFC's.
How friction create harm while cycling?
Friction can be either good or bad depending on where it is. Friction between parts that are meant to stay put is a good thing, friction between parts that are supposed to move is a bad thing. Tires for instance are meant to roll along the road, not slide. Here, friction is good. But then you cone to the hubs. In here, the wheel has to move around the axle. Here, friction is bad. Here, friction will turn effort that would otherwise have gone into moving the bike forward into heat, which is no use to the rider at all.
Organisation discussing the thinning of ozone layer?
The organisation discussing ozone layer is Montreal Protocol. It is meant for ozone only.
What is meant by internal indicator?
Sometimes one of the reactants in a titration act as an indicator; this is an internal indicator. An example is the volumetric technique of permanganometry.
