Is friction a non contact force?
Because it is two surfaces rubbing against each other, in this case it creates heat and possibly static electricity. To touch; contact. If two surfaces rub against each other forcefully this is a contact force.
Is Friction reduced between polished surfaces?
when we polish surfaces, the molecules or atoms of surface come closer to each other so there is no space for fiction so it is reduced but not reduced to zerowe cant reduce friction to zeroWhen we polish a rough surface smoothly,the unequalities gets reduced,therefore friction is reduced
When people come in direct contact with a harmful agent at or near an incident is?
Contamination
Where does the oxygen come from that you are breathing right now?
oxygen can be formed by the electrolysis of water, or by chemical reactions Oxygen is present in air, about 19% by volume, but it is not formed there. Most oxygen is naturally formed in green plants and algea by photosynthesis.
What are contact forces and which forces are contact?
Contact forces are forces that can only have an effect on objects that they touch, such as when you contact a box and apply force to move it. you might apply a contact force to bend, tear, stretch, compress, or twist and abject. Tension force, friction force, and elastic force are examples of contact forces.
Microwelds are formed where?
bumps from two surfaces come into contact.
What Are formed where bumps from two surfaces come into contact.?
microwelds
What is formed where bumps from two surfaces come into contact?
Microwelds
What is formed when bumps from two surfaces come into contact?
Microwelds
What happens to friction if the force surfaces together increases?
the larger the force pushing the two surfaces together the stronger the microwelds will be , because more of the surface bumps will come into contact , to move one surface over an other , a force must be applied to break the microwelds .
When and where do you get friction?
Anytime the surfaces of two objects come into contact.
How often must food contact surfaces that do not come into contact with PHF foods be cleaned?
24 hours
What is the opposing force that resits motion when two surfaces come in contact?
Friction
What happens to friction if the force pushing surfaces together increases?
the larger the force pushing the two surfaces together the stronger the microwelds will be , because more of the surface bumps will come into contact , to move one surface over an other , a force must be applied to break the microwelds .
What is the opposing force that resists motion when two surfaces come in contact?
I believe that would be friction
Why do cam lobs wear?
friction - any time two surfaces come into contact no matter what the lubrication, ther is wear.
Why are metamorphic rocks formed by contact metamorphism usually not as dense as those formed by reg?
Because in contact the rock actually comes in contact with magma, this joins with the rock, so when it cools and become igneous rock, it's denser. In regular, or regional, the rock is formed from intense heat and pressure, but does not actually come in contact with magma.
