How can friction be helpful and harmful? However, Friction can also be harmful, for example, Rubbing two objects together causing friction causes heat, under the right circumstances it could even cause a fire, so in that case it could be good or bad, when you rub two sticks together to make fire, its good, but lets say your engine in your car is low on oil, the friction in the cylinders will eventually cause the motor to over heat and seize up and then you have engine failure and a large mechanic bill, thats bad,

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.

Atom Friction. 1  Although wheels are great for rolling and reducing friction, they couldn't work without friction. 2  It would be really tough just to stand up without friction. 3  Friction can generate static electricity. 4  The harder two surfaces are pressed together, the more force it takes to overcome the friction and get them to slide.

- the dust from frp, grp or other composites is very harmful to the body, and just as bad for electrical components especially motors, i really would not want to cut it with my ts unless you have extremely good extraction and PPE and the right blade which would be a carbide or continuous diamond. the blades can get very hot and damage the material and the blade/tool. i have found a very thin kerf continuous diamond disk on a grinder to be good, but im not sure exactly what you are cutting or ...

- Friction is overcome by the addition of force. But there are some basic ways to avoid excess friction: 1) Reducing friction between moving surfaces by using lubricants suc…h as powders, oil or water. 2) By using surfaces that have less friction such as plastic or teflon where the parts come together.

How Is Friction Helpful to Us? In the second scenario, the ice reduces the friction, which causes you to slip. In the first scenario, there is more friction between your shoes and the concrete. Since friction is a force that works against motion, the friction between your shoes and the concrete works against the motion of you slipping and falling.

friction When one thing rubs and grates against another, it causes friction. That can include two clashing personalities or simply a match striking the matchbox and causing a spark. A form of resistance, friction is caused by a chafing movement between two or more objects. In the 18th century, friction meant specifically a “resistance to motion,” but a few decades later grew to also describe disagreement or conflict. The friction between the brakes and your tires helps stop your car when you're going too fast.

- There are many types of friction, such as air friction or sur … face friction, but all types of friction create a pull on one another. The primary causes of friction are surface roughness, the plowing effect and molecular adhesion.

Q: What causes friction? (and some other friction questions) “Friction” is a blanket term to cover all of the wide variety of effects that make it difficult for one surface to slide past another. There a some chemical bonds (glue is an extreme example), there are electrical effects (like van der waals), and then there are effects from simple physical barriers.

Q & A: What is friction? A: Anna, 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.

- friction is greater between rough surfaces. in order to reduce friction in the moving parts of machines, scientists and engineers use oil and other lubricants. these lubricants make the surface smoother.

Friction Friction is a force that resists motion. It occurs when one object is in contact with another object. When two surfaces are pressed together, the molecules of these surfaces come in contact and experience attractive forces between one another.

How does friction start a fire? Friction converts useful kinetic energy (also called ordered energy) into thermal energy (disordered energy), or heat. Friction gets a bad rap for turning useful energy into useless energy. It's true that a lot of kinetic energy in the world is lost into the atmosphere as heat. But heat isn't always useless. For instance, whenever our hands get cold, we can rub them together and feel the heat from the friction almost immediately.

Definitions &Translations Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: 1  Dry friction resists relative lateral motion of two solid surfaces in contact.

What is friction? Physics definitions There's more friction when the two objects are pushed together harder. If you push your hands together, it's harder to rub them up and down. If you pull the brake lever harder, your bike will stop faster. Because gravity pulls harder on things with more mass, things with more mass have more friction and are harder to move-a cube of iron will be harder to move than a cube of wood.

- this i dont know You can reduce friction by: Adding oil    Friction can be reduced by using smooth surfaces, or by lubrication. Things like oil or grease are lubricants…, and help things to move past each other easily.    You can reduce friction by putting the object on wheels.

- 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.

Physics for Kids 1 Dry Friction - Dry friction occurs when two solid objects touch each other. If they are not moving, it is called static friction. 2  Fluid Friction - Fluid friction involves a fluid or air. The air resistance on an airplane or water resistance on a boat is fluid friction.

Friction Two kinds of friction are static and kinetic. Static friction is when the friction is strong enough to stop movement between two objects. Kinetic friction is when the frictional force is not strong enough to stop all motion.

Friction is a force that slows things down or tries to stop an object moving. Friction causes grip and heat for example the brakes on your bike will be hot after they have slowed down the moving wheel. Without friction you feet would slip on the ground and the tires would slip and flip on the roads, and they both rely on friction to stay put.

- 1 Friction is a catchall word that refers to any force that resists relative tangential motion (or intended motion).  2 Relative tangential motion is a fancy way to say slipping or sliding.  Its direction is opposite the relative velocity (or intended velocity).

- A: Friction is a force that works against motion. While walking, friction helps us maintain our stability and prevents us from slipping. Friction also works the same way with cars and vehicles in general, preventing them from skidding and helping them stop when the brakes are applied.

What causes friction? Why does two objects rubbing together create friction? Why does the fact that two surfaces are touching have any effect on the amount of force required to move either surface? Friction has several origins, and that's what makes it tough to understand. Some friction arises because the surfaces are actually quite rough, at a microscopic scale, and so they tend to catch on each other. Some friction arises because of the microscopic pull of atoms towards other atoms; that effect is the electromagnetic one you are referring to. That's why some of the greatest friction is experienced when two very smooth surfaces touch.

friction Thus, friction is a dual process: on the one hand, it involves the dissipation of energy in overcoming molecular bonds, and on the other, it causes the formation of a surface layer of material with imbedded irregularities.
