You can't say for definite but in general, 2 very lumpy, rough surfaces rubbed really hard against each other would create the most friction.
so you could slow down a car or write with a pencil
in walking
for nailing
for braking
for slowing down something that is rolling
When one object rolls over another object, like when the wheel of a car rolls over the ground.
when braking
we need friction because if there were no friction the objects around us will slide
because you need to slide down the hill....?
F1 cars need friction for their brakes, if they didn't have friction on there brakes then it wouldn't be able to brake.
You need a little friction when you are going down a water slide and much more
It is! To create static electricity you need friction.

yes! you need friction for lacrosse so you don't fall
F1 cars need friction for their brakes, if they didn't have friction on there brakes then it wouldn't be able to brake.
On her feet and hands. That is why they build climbing shoes from sticky rubber. Her belay partner will need friction in their belay device (ATC OR GRI GRI, etc)
than what?
You need high friction so your feet and hands don't slip.
You need a little friction when you are going down a water slide and much more
We would need to know what the friction is to affect to respond to this question.

friction
Yes
