Friction from every day life can help you slough off your layer of dead skin thus exposing the new healthy layer. Daily exfoliating with a loofa and or sponge can also help. Be careful to not over exfoliate or it could be painful.
Gravity? the strength of the floor?
It keeps the roller down and creates friction to allow the roller to move.
It slows the object down.
Mostly, because of the heat of the gasses which fire it. I think air friction and barrel friction play a small part.
Because friction is a force acting against the forward motion of the puck, friction is going to play a role in slowing down the puck as it glides across the ice. The friction is not going to be great enough to stop it instantly, but if not touched by another stick for some time it will come to a stop.
no
sorry to break it to you but that part is already taken!
what role does friction play in some methods of joining
they break down the nitrates and nitrites in the water
they break down the food first then the rest of the digestive system breaks it down more.

It is only because of friction that we can walk or run.
