What happens when the applied force is equal to the kinetic friction?

Presumably, the forces are in opposite directions. In that case, the total force is zero, and there will be no acceleration.

Static friction is a self adjusting force explain?
i think that static friction is the friction onl because of mass and nature of the surface
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
How would the velocity of the book change if the applied force were equal to the sliding friction force?
The book slides with constant velocity.
What is required to get a stationary object moving?
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).
What happens to the total mechanical energy of a system if friction is involved?
No. Kinetic energy is the energy of something moving.***Friction is a force opposite the direction of movement due to the rubbing of surfaces in contact. This rubbing causes heat energy which is usually dissipated into the surroundings and is therefore unavailable to do further work. Heat energy is an increase in the kinetic energy of the molecules BUT again, friction is a force NOT energy.
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.
Is there a force that can go against friction?
No. Friction can only slow an object down. If friction were imparting a force greater than that of the applied forces, then friction in and of itself would actually be causing the object to move, which does not happen.

Why might potential energy not equal the amount of kinetic energy at the end of a reaction?
Heat lose (usually friction).

How do you that forces are balanced when static friction acts on an object?
The other force being applied, opposing to the object's static friction would both be equal therefore the forces are balancing.
How would the velocity of the book change if the applied force were equal to the sliding friction force?
The book slides with constant velocity.

If the friction equals the force why the object moves. why it doesn't stop?
Friction force is equal to the force applied only when the object is not moving or it is just beginning to slide. Once the object has started motion completely, it means that the force applied has exceeded the frictional force
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.
