Some of the good effects of friction are also the bad effects.
Good effects:
- Stops or immobilises objects including cars, trucks and humans from sliding down a slope;
- Allows humans to walk - pushing off from the back foot and not falling over (think about walking on ice or worse, running on ice);
- Allows objects to remain where they are ie remain at rest, to be leant on;
- ...
Bad effects:
- Causes the production of heat between surfaces when the objects move eg car tyres and brakes heat up due to friction. Engines have to be oiled to reduce the friction of the moving parts. If the engine runs out of oil then the motor will seize due to friction (did that once - new engine required);
- Friction causes wear on surfaces that slide on one another - even our shoes wear out due to friction with the ground;
- Friction with air causes air craft, rockets and meteors to heat;

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
What are 2 bad advantagaes of friction?
if it is an advantage then it can't be bad
What is the worst kind of energy?
There is no worst kind of energy. Like most things, energy is neither good nor bad. but all types can have good or bad effects.
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.
What is bad friction in gears?
bad friction is when 2 things rub together .

How is friction good and bad?
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 good effects and bad effects on estuaries?
the good effects on a estuary is the amountof animals and plants it gets. the bad effects are when the animals harm the estuaries and when the water is harmful in the ocean
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.
Are the effects of colonialism on native cultures good or bad?
BAD!!!
