Oil (in car). Grease (in bearings). Silicon. Water.
yes,its fire retardant and sound proof material also
Basket ball shoes work the best because they have the best friction and traction.
There are two most widely used methods to reduce friction__Using lubricants.Converting Sliding Friction into Rolling Friction
The answer you're looking for is, they were both invented by women, however, Stephanie Kwolek, a scientist, didn't actually invent "the bullet proof vest," but instead, she invented Kevlar, a material used in bullet proof vests.
The best-known bullet-proof material is probably Kevlar.
This depends upon the type of material. Varnish is best for wood.
Kevlar is one of the best and well known bullet proof materials. it was originally made to be a material to make a tire but when they made it it was stronger than they thought it would be.

theory can only be a best simulation based on a formula. Fact is material proof
Surface and material affect friction by changing the amount of contact between objects and the roughness of the surfaces. Smoother surfaces with less friction will have less resistance to motion, while rougher surfaces with higher friction will have more resistance. The type of material can also impact friction, as some materials have a higher coefficient of friction and will create more resistance when in contact.
yes if you add bullet proof material
The type of friction between air and another material is called fluid friction or air resistance. It is the force that opposes the motion of an object as it moves through the air.
A mile of granite.
Different materials have different coefficients of friction because the materials have different microscopic bumps and valleys which cause the friction to begin with. Coefficients of friction are constant for each material.
Graphite
The wearing away of material by friction is called abrasion. It occurs when two surfaces rub against each other, causing particles to break off and wear down the material.
