Friction is helpful in situations like when you are standing on a hillside. Static friction between your shoes and the surface are stopping you from slipping. Friction is not helpful in situations like when you are pulling something heavy. Some of the energy you are putting into pulling is going into heat from kinetic friction and making your job more difficult.

∙ 14y agofriction is what helps you propel the bike forward - if not for friction between the bike's wheels and the pavement, the tires would just spin in place and the energy you put into pedalling would not translate into forward motion.
friction can be bad if you fall off the bike - in this case the friction between your body and the pavement could scrape off your skin - ouch!
on the other hand, without that friction, you would continue moving across the ground and not stop. ...

When is heat from friction helpful and when is it harmful?
Helpful:1. We use it to brake our cars2. We use it to fly our airplanes. (The friction of air on the wing causes the plane to stay airborne).3. We would slip and fall if there were no friction between the ground and our shoes (demonstrated by an icy sidewalk...).4. We wouldn't be able to turn a doorknob without friction. (Our hand would just slide off of it.)5. We can warm our bodies by friction. (When campers get lost, they can rub their chest, arms and legs to create warmth by friction)Harmful:1. Our cars would get much better gas mileage without tire and air friction.2. There would be no more skinned knees if friction didn't exist. (Like when you are skating or playing football.)3. We wouldn't have to worry about clothes chaffing us in dry weather if there were no friction.4. We could do some pretty amazing dance moves without friction. (The Electric Slide would last forever....)5. Our shoes would last a lot longer without friction.
How can harmful friction be reduced?
Separate the surfaces undergoing friction; this is what hovercrafts and hydrofoils do.Put some lubricating substance between the surfaces undergoing friction; this is the fuction of oils and greases.Coat at least one of the surfaces with a substance that presents less friction; the plastic known as Teflon is sometimes used for this purpose.
