The direction of kinetic friction is always?
against motion For example, if I push a box to the left, kinetic friction is going to the left.
What is static friction in sliding friction?

How is the direction of the force of kinetic friction related to the direction of an objects morion?
The force of kinetic friction always acts in the direction opposite to the direction of an object's motion. It resists the motion of the object by acting in the direction that opposes its velocity.
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!
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
When a body slides over a surface the kinetic friction and static friction related as?
The kinetic friction is the force that opposes the motion of an object as it slides over a surface, while the static friction is the force that prevents an object from moving when at rest on a surface. Kinetic friction is generally weaker than static friction for a given surface.
Who is creator kinetic friction or limiting friction?
Not God.. Friction was always there, that's why planets exist.
The direction of kinetic friction is always?
against motion For example, if I push a box to the left, kinetic friction is going to the left.
How the direction of the force of kinetic friction is related to the direction of an of an objects motion?
Friction always acts opposite to the direction of motion.

How does the force of friction act relative to an object and motion?
Friction is a force that is created whenever two surfaces move or try to move across each other. -Friction always opposes the motion or attempted motion of one surface across another surface. -Friction is dependent on the texture of both surfaces. -Friction is also dependent on the amount of contact force pushing the two surfaces together normal force. -On the level of surface, the normal force is always equal and opposite to the wieght. -The force of static friction cancels out the applied force right up to and including when static friction reaches its maximum. -For applied forces greater than the maximum force of static friction the block starts to slip and then the value for friction becomes kinetic friction and the box is then under a net force so it accelerates to the right.
Definition kinetic friction?
Friction generated between two dry surfaces in contact during motion. Kinetic frictionis a product of the coefficient of kinetic friction and the normal reaction force. It assumes a constant value regardless of the amount of applied force or the speed of the motion. Its value is always less than the limiting friction between the same two surfaces.
How is the direction of the force of kinetic friction related to the direction of an objects morion?
The force of kinetic friction always acts in the direction opposite to the direction of an object's motion. It resists the motion of the object by acting in the direction that opposes its velocity.

Why does rough surface offer greater friction than a smooth surface?
Almost always.

What is friction what causes it and wahat does it do?
Friction is a force that acts on all touching objects. Friction is caused by the roughness of on object. Even if an object feels smooth to the touch, it will never be perfectly smooth because there will always be microscopically small peaks and valleys at the atomic level. What friction does is essentially try to prevent an object from moving or continue moving. There are two types of friction, static and kinetic. Static friction must be overcome to get something moving, kinetic friction must be overcome to keep something moving. They both have values that depend on the two surfaces touching and are referred to as the coefficient of their respective term. Note: the coefficient of static friction is always higher than that of kinetic for the same two materials.
