∙ 11y agodambel! it is 0.78 for static and 0.53 for kinetic.

∙ 11y agoi got an answer of 0.49 in average of 5 tests in an experiment that i did in college not sure if it is exactly that but should but near enough

∙ 11y agoFriction exists between two solid surfaces.
Air exists in gaseous state. So coefficient of friction between air and aluminium(or any other solid) does not exist.

What pattern do you notice about the values for the coefficients of friction?
The value of static friction is higher than the value of kinetic (sliding) friction.
What are microwelds?
Table of CoefficientsThe coefficient of kinetic friction is always less than or equal to that of static friction.The table below shows many coefficients of friction. Notice that each value is always given for a pair of surfaces. Friction doesn't work unless there are two surfaces.Also note that there are values shown for both static friction and kinetic friction. Static friction deals with starting to move something, while kinetic friction deals with keeping something moving once it's already in motion.In each case, it's also important to note that the coefficients of kinetic friction are always less than or equal to the coefficients of static friction. objectWrite('');Coefficients of Friction for Pairs of SurfacesSurfaces in ContactCoefficient of Static Friction (s)Coefficient of Kinetic Friction (k)Wood on wood0.50.3Waxed ski on snow0.10.05Ice on ice0.10.03Rubber on concrete (dry)1.00.8Rubber on concrete (wet)0.70.5Glass on glass0.940.4Steel on aluminum0.610.47Steel on steel (dry)0.70.6Steel on steel (lubricated)0.120.07Teflon on steel0.040.04Teflon on Teflon0.040.04
What are the 2kinds of friction?
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
How is static friction and kinetic friction differ from each other?
They are different because static means "not in motion" and kinetic means "in motion". Kinetic friction means friction that is moving and static friction means friction that is not moving.
Which form of friction is harder to overcome static or kinetic?
The static coef. of friction is greater than the kinetic coef. of friction.
What two kinds of coefficients of friction exist?
Static and kinetic coefficients
What pattern do you notice about the values for the coefficients of friction?
The value of static friction is higher than the value of kinetic (sliding) friction.

They are different because static means "not in motion" and kinetic means "in motion". Kinetic friction means friction that is moving and static friction means friction that is not moving.
Can coefficient of friction be more than 1?
Yes.This would just mean the force of friction could be greater than the normal force.Also, keep in mind that the static coefficients are greater than or equal to the kinetic coefficients for the same two surfaces.Some surfaces with higher than 1 static friction coefficients include:Platinum on platinum (1.2)Cast iron on cast iron (1.1)Silver on silver (1.4)Rubber on various surfacesNote that it's just that most surfaces have a both coefficients below 1. Inclusion of Rubber in the list above gives us the clue that it's all about being "sticky" or "slippery"!
Which form of friction is harder to overcome static or kinetic?
The static coef. of friction is greater than the kinetic coef. of friction.
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.
Which type of friction is usually greater static friction or kinetic friction?
Usually static.
A horizontal force of 40 newtons will just start a 600 newton empty sled moving across packed snow what is the coefficients of static and kinetic friction?
static friction= normal contact force*coefficient of static friction 40 = (600*9.8) * CSF CSF=40/(600*9.8) (you can calculate that yourself, i cant be bothered) there isn't enough info to work out the coefficient of kinetic friction
Which coefficient of friction is greater static or kinetic?
static usully greater then kinetic
Is kinetic friction the hardest friction to overcome?
No, static friction is generally stronger than kinetic friction.
