It depends what you want to do with it. Friction generates heat, which can be good (if you are cold), or bad (if you are not). Friction slows down movement, which can be good (if you are about to crash into a tree with your car), or bad (if you need high performance in an engine for instance).
rubbing your hands together
When you fall and friction causes you to scrape or tear yourself. At least it stops you, painfully.
Relative to its surface, friction is constant (this is known as the friction constant). The speed is decreasing on an object because friction is acting on it over a period of time, not because friction is getting stronger.
Good: Driving, Walking, Writing and Eating Bad: Heat parts, Wear Things Out, Wastes Energy and Smoking
bad friction is when 2 things rub together .
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
it depends on the curcumstances but if there was no friction you wouldn't be able to grip anything.
heskey time
its good
It stops you slipping.

No!! time can never slow down

It is because of friction.
