which type of friction forces are the strongest and the weakest?
sliding frictionrolling frictionstatic frictionfluid friction
Is static friction stronger than rolling and sliding friction?
It had better be! Otherwise, nothing could ever start sliding ... as soon as yourpull on the string becomes strong enough for the object to break free of thestatic friction and begin to slide, the force of kinetic friction would take over,and it would suddenly be even stronger!
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.
Is friction necessary for motion?
No. Friction is just necessary for controlling motion.
How can you realate friction?
rube your hands together you just created friction
Will the total energy of a vibrating body is conserved if friction occur?
Energy is always conserved. When friction is present, the energy usually just turns into heat.

How does friction help and hurt you?
Think of a car, friction causes air resistance on the car and results in lower gas mileage, but without friction, the tires would just spin in place and the car would not go anywhere.
What are some facts about friction?
Friction is a force, of resistance, that takes place when two or more objects make contact and when there is movement with one another. Friction keeps your feet on the ground and prevents you from slipping. Fricition is just like gravity.
What is limiting value of friction?
The maximum friction that can be generated between two static surfaces in contact with each other. Once a force applied to the two surfaces exceeds the limiting friction, motion will occur. For two dry surfaces, the limiting friction is a product of the normal reaction force and the coefficient of limiting friction.
Who invented friction?
Friction was not invented just discovered

How does friction help us from place to place?
The use of friction is a science question, specifically a Physics question, not really a History and Politics question, unless you mean that friction is necessary in conversation, in order to be understood -- that is a profound question, but I doubt that you mean that, by your friction question. Assuming that you want a science answer: Friction is necessary, in order for you to have something to push against. You need that friction in order to place your foot down in one place, long enough for you to push off to someplace else. If there were no friction, you would just slide all over the place, and get nowhere, like sliding on ice. If you ever tried to get your footing, to stand up, while getting up from icy ground, ground that's covered with ice, then you have experienced what I'm talking about. The same principle applies to cars and tires: the tires have to be at least a little bit sticky, in order for the car to have enough traction, for the engine to get the car moving. Otherwise, you just spin your wheels.
Why could cars not move without friction?
When the wheels of a car turn, friction causes the wheels to push back on the road, which in turn causes the road to push the car forward. Without friction the wheels would just spin in place. You can sometimes see this occur on icy roads, where there is very little friction.
Why is fricton necessary to drive a car on a road?
Actually the good effect of friction is: if you drive a car you can make it stop, friction makes it stop. But the bad effect is: friction wears out machines so you can replace it. Hope it helps! :) Also with no friction the tires would just spin and go no place, and steering would be a problem.
