Q & A: What is friction? Friction is a force which causes the motion between two surfaces to be reduced. [see below for a more general discussion/ mw] Friction happens because most surfaces are not perfectly smooth. Even a table top which may appear smooth has little bumps in it if you looked at it with a really good microscope.

injustice Injustice and unjust use different prefixes, as French injustice was borrowed into English, while unjust was formed as un- + just. The spelling injust, from French injuste, is very rarely used, and unjustice, from un- + justice, is nonstandard. justicelessness.

What is viscosity? (Redirected from Viscous friction) The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept of thickness; for example, honey has a much higher viscosity than water. Viscosity is a property arising from collisions between neighboring particles in a fluid that are moving at different velocities.

FRICTION Dictionary entry overview: What does friction mean? • FRICTION (noun) The noun FRICTION has 3 senses: 1. a state of conflict between persons 2. the resistance encountered when one body is moved in contact with another 3. effort expended in moving one object over another with pressure Familiarity information: FRICTION used as a noun is uncommon.

friction n the resistance encountered when one body is moved in contact with another. the wearing down of rock particles by friction due to water or wind or ice. the friction between a body and the surface on which it moves (as between an automobile tire and the road)

friction Sliding friction. If the component of the force applied to a body that lies in the plane of contact between two bodies is insufficient to cause one body to slide with respect to the other, the frictional force developed is called the static friction (OA in Figure 1).

- Friction. Friction is a resistance to motion that is opposite the direction of travel. It is caused when two surfaces are in contact. Since friction acts to slow down a moving object, it is called a resistive force. This is different than active forces that cause objects to accelerate or change direction. Friction is mainly caused by surface roughness. The classic law of friction states that friction is the product of a coefficient and a force.

Static Friction: Definition, Formula & Examples If you try to push your couch across the room, the first push is the hardest part. Maybe people assume that's nothing more than psychological, but there really is a physics reason for it. The reason is static friction. Friction, in general, is a force that makes it harder for two objects to slide alongside one another.

Definitions &Translations ⁕Fluid friction describes the friction between layers within a viscous fluid that are moving relative to each other. ⁕Lubricated friction is a case of fluid friction where a fluid separates two solid surfaces. ⁕Skin friction is a component of drag, the force resisting the motion of a solid body through a fluid. ⁕Internal friction is the force resisting motion between the elements making up a solid material while it undergoes deformation.

- Friction is also a force that, when unbalanced, can change the velocity of an object. What You Will Learn • The magnitude of the force of friction can vary. • Kinetic friction is a force that, when unbalanced, can change the velocity of a moving object. • Static friction balances an applied force and can prevent motion. • Friction can be both harmful and helpful.

- What is static friction and kinetic friction? Static friction is the friction between two objects that are not moving relative to each other (eg: a desk on the floor not moving), kinetic friction is the friction between t…wo objects that are moving relative to each other (eg: a desk sliding on the floor)

Friction 1 Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. 2  Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces.kin friction arises from the friction of the fluid against the skin of the object that is moving through it. Skin friction arises from the interaction between the fluid and the skin of the body, and is directly related to the area of the surface of the body that is in contact with the fluid.

coefficient of friction coefficient of friction. A measure of the amount of resistance that a surface exerts on or substances moving over it, equal to the ratio between the maximal frictional force that the surface exerts and the force pushing the object toward the surface.

- Friction is caused by the degree of roughness a surface possess. The more the surface is rough, it cause more friction. Impetiments in surface as they make conact. Nothing is perfectly smooth that's has mass Friction is what is known as the resistance of a solid (in comparison to air resistance and water resistance).

- Gravity is the name we give the force of attraction between two masses, and it arises as a consequence of mass. If something has mass, it has gravity, de facto. Friction can be looked at as a force resisting any increase or any maintenance (continuance) of motion-but do not confuse this with inertia.ravity and friction is different because gravity is the force of something thats going downward and friction is the force that is being pushed if touching the ground.

How is friction increased and decreased? Friction, as a physical term, is the force that opposes to movement when two objects contact each other in the shpere of cinematics. It is produced by the contact between atom … s. Friction as a physical property cannot be decreased nor increased.But, by placing other object between these initial two can give different friction between those two, reducing the force that opposes to movement and therefore, at the end of the ecuation, reducing friction.riction as a physical property cannot be decreased nor increased.

friction noun. There is a great deal of friction between the politicians. There is a great deal of friction between the politicians. The definition of friction is conflict or unease created when two people of opposing views or ideals come together or the resistance that occurs when surfaces rub together. 1  An example of friction is when Republicans and Democrats get together and discuss politics.

Ask Us Friction in Space. Yes, when two surfaces rub together in outer space, there will be friction. Friction is a surface effect and doesn't depend upon there being air. There is also a force like air resistance from the very sparse gas in space, but it will be very, very small, since space is a very good vacuum.he density of matter in our Galaxy is about 1 particle/cm3 (in the disk, with the halo being less dense). The density of matter in intergalactic space (between galaxies) is about 2 x 10-31 gm/cm3, mainly hydrogen. At these densities, I don't think one has to worry about friction.

Friction In Our Lives Context: When two surfaces are in contact, friction is always present. Definition: To pull along with difficulty or effort. Context: An airplane comes to a stop because of the drag or pull on it as it moves through air and across a surface. Definition: Strength or energy exerted. Context: A force can change the direction of motion, increase the rate of motion, slow down motion, or stop it all together. Definition: The rubbing of one object or surface against another; the force that resists motion between bodies in contact. Context: Bicycle brakes use friction to stop the wheels from turning.
