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.
You can change friction by the material. e.g ice, low friction. carpet high friction.Or you could add a lubricant :D

Friction is good for two reasons, both are related. 1) Friction allows your car to stay on the road. Bigger tire surface translates to more friction=better handling. Also 2) friction stops your car (brakes). The bigger the contact surface from the tire (the tire touching the road) and the better the braking system (drum brakes or disk brakes), the quicker your car will stop.
There are many reasons why friction is an advantage to human motion. Friction helps humans to stop when they need to stop.
it is because of friction. friction is a force that opposes the relative motion of two surfaces in contact.
Matt Eastman's book has a pretty good schematic.
track. anything that has to do with running. you use friction when running. but as for the 5 without use of friction then i have no idea
cuz he could
1. Static2. Sliding3. Rolling4. Air5. Fluid
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.
Friction, but that is one of the reasons why it causes a moving ball to stop. Friction comes from the grass and sometimes the dirt/soil.
it depends on the curcumstances but if there was no friction you wouldn't be able to grip anything.
