Advantages and disadvantage of friction?
Advantages of friction 1. It enables us to walk with out slipping. To enhance friction, it is advisable to use shoes with rough sole while walking on slippery floors. For a similar reason, crutches are provided with rubber tips at their bottom to provide sufficient friction. 2. The breakers and tiers of our cars and bicycles depend on friction to function properly. 3. The ridges in the skin of our fingers and palms enable us to grasp and hold objects due tofriction. 4. To prevent patients being uncomfortable in bed rubber sheets with spongy under surfacesare placed over mattresses. The friction between the spongy under surfaces and the mattress prevents the rubber sheet from slipping and wrinkling. 5. Nails and screws are held in wood by friction. 6.High resistance in storage. 7.A horse can pull a cart unless friction furnishes him a secure foothold. Disadvantages of Friction 1. Production of heat, noise and wear in machine parts rubbing against one another. 2. Heat produce by friction may be sufficient to cause the abrasion of the skin, resulting in friction burn. Rubber tubes such as gastric and duodenal tubes, rectal tubes and catheters may burn or irritate the membrane over which they pass unless measure are taken to prevent friction. 3. Friction reduces the efficiency of engine and other machines. 4.due to friction,engines of auto mobiles consume more fuel which is a money loss.
When a body slides over a surface the kinetic friction and static friction related as?
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
Advantage of friction?
there are many advantages of friction. It helps us in driving, walking, writing, holding objects, etc.
Is rolling friction greater than sliding friction?
Typically not. However rolling friction is somewhat of a myth. Rolling friction is actually caused by static friction. There are really only two types of friction: Static and Kinetic. That's it! Rolling friction is caused by static friction and the coefficient of friction (which determines its strength) is dependent upon the two materials of interaction.
What are the advantages and disadvantages of friction?
Advantages of FrictionIn some situations, friction is very important and beneficial. There are many things that you could not do without the force of friction.Walking: You could not walk without the friction between your shoes and the ground. As you try to step forward, you push your foot backward. Friction holds your shoe to the ground, allowing you to walk.Writing: Writing with a pencil requires friction. You could not hold a pencil in your hand without friction. It would slip out when you tried to hold it to write. A pencil eraser uses friction to rub off mistakes written in pencil lead. Rubbing the eraser on the lead wears out the eraser due to friction, while the particles worn off gather up the pencil lead from the paper.Driving car: Your car would not start moving if it wasn't for the friction of the tires against the street. With no friction, the tires would just spin. Likewise, you could not stop without the friction of the brakes and the tires.Friction Pen: Inventors have invented useful items like the friction pen/highlighter. You are able to erase the pen/highlighter mark. The problem is that the rubber at the back gets dirty easily.There wouldn't be a Universe without friction.Disadvantages of FrictionFriction can cause problems or be a nuisance that you try to minimize.Makes movement difficult: Any time you want to move an object, friction can make the job more difficult. Excess friction can make it difficult to slide a box across the floor, ride a bicycle or walk through deep snow. An automobile would not move forward very well unless its friction was not reduced. Oil is needed to lubricate the engine and allow its parts to move easily. Oil and ball bearings are also used in the wheels, so they will turn with little friction.Wastes energy: In any type of vehicles as a car, boat or airplane--excess friction means that extra fuel must be used to power the vehicle. In other words, fuel or energy is being wasted because of the friction. Fluid friction or air resistance can greatly reduce the gas mileage in an automobile.Heats parts: The Law of Conservation of Energy states that the amount of energy remains constant. Thus, the energy that is "lost" to friction in trying to move an object is really turned to heat energy. You've seen how people will try to start a fire by vigorously rubbing two sticks together. Or perhaps you've seen an automobile spin its wheels so much that the tires start to smoke. These are examples of friction creating heat energy. Just rub your hands together to create the same effect. Besides the problem of losing energy to heat, there is also the threat of a part overheating due to friction. This can cause damage to a machine.Wears things out: Any device that has moving parts can wear out rapidly due to friction. Lubrication is used not only to allow parts to move easier but also to prevent them from wearing out. Some other examples of materials wearing out due to friction include the soles of your shoes and a pencil eraser.Carpet burn is because of friction.CompromiseA compromise is needed between too much friction and not enough.For example, if you wanted to slide a heavy box across the floor, you would want to reduce the friction between the box and the floor, so that it would be easy to move. Lubrication of some sort is often a way to reduce friction.Friction is necessary in many applications to prevent slipping or sliding. But also, it can be a nuisance because it can hinder motion. A good compromise is necessary to get just enough friction or a proper combination of frictions

friction has many advantages walking,moving of a vehicle etc...............

What are the advantages and disadvantages of friction piles in construction?
1) In machines the mechanical parts which rub with each other wear out. 2) Due to friction between the sole of the shoe and the floor the sole wears out. 3) Tyres of vehicles wear out because of friction. 4) Energy is wasted in overcoming the force of friction.
State any two advantages of friction?
1) Prevent things from moving past each other (while touching) 2) create heat
How is friction important in your lives?
when you walk; wheels roll to move cars; you grasp something in your hand; cars brake; these are all because of friction. Really there are advantages of friction.
What are advantages of wheel?
Rolling friction is less than sliding friction so it is easier to move heavier objects using wheels.
What is the advantages in friction?
Without friction. everything would slide about, similar to what happens when you walk on ice. Friction enables objects to remain in position, keeps cars from skidding etc.
What are the advantages of frictional force?
it is because of friction that we are able to stand and sit anywhere.
