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.

What are some situations where friction is good and some some where friction is bad?
In situations where you want to create heat or dissipate kinetic energy, friction is usually a good thing. Friction when rubbing your hands together creates heat, which you appreciate, and friction between your brake pad and brake disc slows down your car, which is also a good thing. In situations where you want to maintain kinetic energy or minimize heat, friction is usually bad. Air friction slows down a glider, limiting its range, and mechanical friction in a car rolling on a flat surface causes it to stop without the brakes being applied.
How does friction affect shoes?
Low friction is slippery high friction has good traction. In the sport of Curling (gliding those heavy granite stones on ice towards a bullseye) one shoe has low friction (to slide on the ice) the other has high friction (to propel the player).
What are good and bad things about veterinarians?
bad-they molest your pet good - they treat him/her good
Is positive bad or good?
In mathematics it is neither bad nor good. Elsewhere, it is taken to be good.
What are the good and bad things about clocks?
good: usful for time managments BAD: uses battery
What is bad friction in gears?
bad friction is when 2 things rub together .
Why is friction both good and bad?
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).
What are some situations where friction is good and some where friction is bad?
Good: Driving, Walking, Writing and Eating Bad: Heat parts, Wear Things Out, Wastes Energy and Smoking
What are some examples of good and bad friction?
jacking off
How friction create harm while cycling?
Friction can be either good or bad depending on where it is. Friction between parts that are meant to stay put is a good thing, friction between parts that are supposed to move is a bad thing. Tires for instance are meant to roll along the road, not slide. Here, friction is good. But then you cone to the hubs. In here, the wheel has to move around the axle. Here, friction is bad. Here, friction will turn effort that would otherwise have gone into moving the bike forward into heat, which is no use to the rider at all.
What is situation without friction good or bad?
For us, it would probably be bad. Without friction, it would be nearly impossible to get around. imagine walking around on ice all day, but worse.
Why is friction a bad thing?
Friction isn't always bad, but when engineers try to avoid or reduce friction, it is because of the energy lost due to friction.

What are some bad effects of friction?
Grazing your knees and hands when falling over and sliding on a hard surface is caused by friction with the ground. A spacecraft returning to earth will heat up to red hot due to friction with the atmosphere. These are just two bad effects of friction. But, there are good effects, too. Friction from your vehicle or bicycle brakes will bring you to a stop! Friction from your tyres and the road surface will prevent you from skidding.
Is friction good for machines?
Some machines need friction to operate. Brakes, grinders, traction wheels, and others all rely on friction to work. In other cases, friction is bad. electric and fuel-fired powerplants for example, are all designed so as to minimize friction. That's why the lubricant industry exists!
