We can work together with friction by applying more force than frictional force. yes it cause a great energy lose but it also helps us in walking with good grip and also helps in grinding creals into flour
Whenever you use energy that is work, and to create friction work must be applied to rub two things together, and sometimes fast enough to create sparks depending on the two objects you rub together.
No, velcro needs friction to function properly. The hooks and loops on velcro fasteners grip each other when pressed together, and this requires friction to create the necessary force for them to engage and hold together. Without friction, the hooks and loops would not interlock securely.
the two surfaces rub together from the grip of the tyres
The formula for calculating the work done by friction is: Work Force of friction x Distance.
No, We cannot do work on friction less surface
The prefix for friction is "co-", which means together or mutually.
bad friction is when 2 things rub together .
when 2 surfaces rube or slide together the more smooth the less friction
The friction produced by rubbing your hands together is kinetic friction, which occurs when two objects are moving relative to one another. This type of friction converts kinetic energy into heat energy.
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.
rubbing your hands together produce heat that is friction.
A example of friction is rubbing your hands together the heat you feel is friction. Oh dont be a shat head.
