as a result of Rheumatoid arthritis some of my joints have lost a lot of their cartilage. the result is extra friction which deforms the joints in the bone and causes some serious pain.

The two common forms of friction between two sliding surfaces presented in this course are?
Friction refers to the resistance that one surface or object encounters when moving over another. The two common forms of friction between two sliding surfaces are static friction and rolling friction.
Why do you put oil in a machine?
To reduce friction, which is a resistance between two surfaces in contact. The points of contact between moving parts in a machine create heat (which is actually a desired effect in a flintstone, in which one strikes a flintstone with another rock to create heat as a means of starting a fire) and cause damage in their grinding against one another. Oil reduces the friction, which reduces the heat generated and the damage from the moving part surfaces grinding against one another; this reduction in friction is called lubrication.
Identify the area of the foot that is usually affected by gout?
Gout most often affects one joint in the big toe (i.e. podagra).
What is the difference between heredity and mutation?
Heredity is how information is based from one generation to the next; encoded in the DNA molecule. A mutation is a mistake that is made in the DNA. Most mutations have no affect, some are harmful, and a small number confer an advantage. Natural Selection works to eliminate the harmful and enhance the beneficial.
How can you pass arthritis?
Arthritis is a condition, not an illness, or a contagious or infectious disease. Therefore, no one can 'pass' arthritis onto anyone else. Arthritis affects the bones.
What is one way harmful way friction affects cars?
Cars don't get better gas or mileage.
What is one harmful way friction affect a car?

Does friction affect your life?
Yes, because with out friction everything and/or every one would be slipping on the ground.
What are some examples of friction occurring in everyday life?
ice skating on ice ,is one friction occurring
Friction and speed?
Speed is how fast something is moving. When to things are traveling at the same speed and rubbing together, they can cause friction.
What are examples of harmful friction?
1. The soles of your socks wearing out 2. The gears in you care will wear down if not lubricated with oil 3. Holes in your jeans 4. Scraping your knee Harmful friction consists of two surfaces in motion, yet not in harmony with each other or one surface in motion against a fixed surface, which causes a wearing of one or both surfaces. Examples of harmful friction would be an abrasion to the skin from a person sliding on a rug or friction between a foot and a shoe creating heat and a blister in the skin of the foot. This is wrong. DONT USE THIS INFORMATION There are many examples of harmful friction. This can include the scrapes and cuts your encounter when falling down on the sidewalk. This can also be found in engines that are not properly lubricated causing them to heat up and malfunction.
How can harmful friction be reduced?
Separate the surfaces undergoing friction; this is what hovercrafts and hydrofoils do.Put some lubricating substance between the surfaces undergoing friction; this is the fuction of oils and greases.Coat at least one of the surfaces with a substance that presents less friction; the plastic known as Teflon is sometimes used for this purpose.
What is a postural disorder?
A postural disorder is one that affects the shape of the spine of a person. This disorder is often harmful or annoying to the host.

What is one way friction affects a car?
Creates heat in the engine (friction of moving parts creates heat) Reduces efficiency (friction in the drivetrain, as well as air resistance, slows the car down) Causes the tires to wear out (friction between the road and the rubber causes the rubber to wear)

What is one helpful way friction affects a car?
Brakes use friction to stop the car. . The serpentine belt uses friction between the belt and the pulleys to power the secondary systems (water pump, alternator, power steering pump, A/C pump, etc.)
