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.
the two surfaces rub together from the grip of the tyres
Kinetic friction.
Friction will work against force
An example of friction is when you rub your hands together or when you rub two sticks together it makes fire
No, We cannot do work on friction less surface
Friction
rube your hands together you just created friction
when 2 surfaces rube or slide together the more smooth the less friction
bad friction is when 2 things rub together .
rubbing your hands together produce heat that is friction.
Increases friction
