What friction is used when an object sits still?
Static friction resists an object from moving when at rest (still) with respect to the surface it is resting on or in contact with. Kinetic friction, or dynamic friction, (normally what we think of when we say 'friction') describes the friction that occurs when one body moves relative to another body and when both bodies are in contact with each other.
What are the classifications of friction?
there are 2 types: 1)static friction and 2)kinetic friction
What are the two main causes of friction?
Static friction, which is the friction that needs to be overcome to get an object moving ( different values on different surfaces ), and kinetic friction, which is the friction imparted to the object as it mover along ( different values for different surfaces ).
How friction affects motion?
Friction is a very helpful thing and with out it you couldn't move, speed up, slow down, change direction, bend, or twist. Without friction nothing would ever happen. Friction can oppose motion or it can make it difficult for an object to move across a surface. Friction both helps an hinders every thing we do.the object would not move without frictionThe friction acts in the opposite direction to that of direction of motion.So friction slows the object and if no external force is applied the object will come to stop.Friction is a force that opposes the direction of motion between two materials. It is parallel to the surface your object is touching. Friction depends on the coefficient of friction and the normal force (force exerted perpendicular to the surface your object is on; opposes gravity on a flat surface). There are two kinds of friction: static and kinetic. Static friction must be overcome in order to move an object. Once the object is in motion the friction acting on it is called kinetic. Static friction has a threshold of force that is needed to get the object moving but once the object is in motion it can be moved at a constant velocity with less force required.

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 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.
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.

What is static frictions?
In static friction, the frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome. In kinetic friction, the frictional force resists the motion of an object. ... The frictional force itself is directed oppositely to the motion of the object.

What kind of friction is wheels rolling on a car?
kinetic friction, and this motion creates thermal energy from this friction. However the wheels moving on a car is directly created from the work of a combustion engine which creates multiple types of friction, chemical and thermal are the two major types.
What are the similarities between charging by induction and friction?
Drag, when referring to Air Resistance, is a type of friction. When an object flies, it comes in contact with air that it has to push out of the way. Since energy is always transferred (never created nor destroyed), the moving object loses some energy/force/velocity when rubbing against the passing air.The frictions that we are more aware of are kinetic and static friction. Static friction is what holds an object in place when another force is acting on it. For example, when you have a book on a table and slope it, the book takes a bit to start moving. However, if you hold the table at a lesser angle and touch the book lightly, it will start to move. This is the difference between static and kinetic frictions.
