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).
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 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 places don't you need friction on a sleigh?
Between the runners and the snow.
What is the force that reduces a runners speed sliding into home plate?
Friction
Is Boars are fast runners and good swimmers?
Are fast runners good swimmers
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 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.
