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).
Name some ways that friction can be helpful and some ways it is harmful?
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.
What are 2 bad advantagaes of friction?
if it is an advantage then it can't be bad
Describe good and bad effects of friction?
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;...
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.

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 can you learn from the book of Pollyanna?
You can look for the good in bad situations.
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.
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.
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!
How many people have a bad life?
We humans have a perception about our lives.God has given us some good and some challenging situations in our lives.Apply our minds in such a way that we come out of every problem.History is full of instances when great man had taken their misfortunes for making there life purposeful for mankind. Perceiveing situations in our life as good or bad, is in our minds.Get up and face these situations with calm and never dying attitude.Best of luck for a bright future.
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.
