When is friction not good?
Friction is not good when it leads to excessive wear and tear on machinery, causes overheating, or decreases efficiency in a mechanical system. In some cases, too much friction can also result in loss of energy and performance.
Does friction increase as speed decrease?
Relative to its surface, friction is constant (this is known as the friction constant). The speed is decreasing on an object because friction is acting on it over a period of time, not because friction is getting stronger.
Friction and motion occur at the same time?
Friction is a force that opposes motion, so they often occur simultaneously. When an object is in motion, friction acts in the opposite direction to slow down or stop the object. The amount of friction present can impact how an object moves.
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).
Why is friction good for shoes?
Answerit keeps you from slipping and falling on your butt.AnswerHave you ever tried to walk on ice? Having no friction would be like that but worse, much worse.
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 is the friction of moving objects?
its good
What is good about of friction?
It stops you slipping.
Would it be good if there is no friction?
it depends on the curcumstances but if there was no friction you wouldn't be able to grip anything.
What is the equation of friction when checking for the effects of wax polish on friction?
heskey time
Does time have friction?
No!! time can never slow down
What would be a good title for gravity friction magnetism?
'Gravictism'? (Formed from Gravity, Friction and Magnetism)
Why do you have good grip in your shoes?
It is because of friction.
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 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.
Where is friction used for good in machines?
in clutch discs
