What kind of friction is the force that sliding objects experience?
Friction refers to the resistance that one surface or object encounters when moving over another. The kind of friction that sliding objects experience is sliding friction.
What is wanted friction?
This presumably refers to friction which we find useful. For instance, if you stand on a ladder which is leaning against a wall, it is friction which stops the ladder from slipping. When you walk, friction between your shoes and the ground enables you to push yourself forwards. If the friction is not big enough, you just slip, as on ice.
What refers to the relative lightness or darkness of surfaces?
Value.
What is friction and causes?
Friction is the pull between two or more objects that causes the objects to slow and eventually come to rest. There are many types of friction, such as air friction or surface friction, but all types of friction create a pull on one another.The primary causes of friction are surface roughness, the plowing effect and molecular adhesion. Surface roughness is when serious abrasion occurs due to the roughness of the materials in contact. The plowing effect involves deformations of the objects that cause resistance to movement when the materials are relatively soft. Adhesion refers to the molecular force that results from two materials brought into close contact with one another. To slide objects against each other, it is essential to break the adhesive bonds between them. According to recent scientific studies, friction occurs because of adhesive forces between materials. Ultra-smooth and sticky materials fall under the molecular adhesion category. There are varying degrees of surface roughness in solid materials. Even a smooth surface has small bumps that interfere with sliding motion. When the surfaces of two hard, solid materials are very rough, friction occurs due to the abrasion that happens when two objects slide against each other. Deformations are another cause of friction. Deformations form when soft materials deform under pressure and lead to an increase in resistance to motion. For example, when a person stands on a rug, he sinks in slightly, causing resistance as he drags his feet along the rug's surface. Resistive force is created, and friction occurs when the deformation becomes large.
What will oppose most forces and slow objects?
That refers to friction.
The two common forms of friction between two sliding surfaces presented in this course are?
Friction refers to the resistance that one surface or object encounters when moving over another. The two common forms of friction between two sliding surfaces are static friction and rolling friction.
Why is the friction of rolling bodies less than that of sliding bodies?
Sliding friction is the force impeding movement as a result of two surfaces rubbing against one another. Imagine pushing a cardboard box of books across a concrete garage floor. Rolling friction refers to the frictional forces between a rolling tire and the pavement. The tire gets warm and an inflated tire rolls easier. The sliding friction is much more difficult to overcome than rolling friction.
How does rolling friction differ from sliding friction?
friction is a eorce of contact between two surfaces which opposes motion of objects over one another. In rolling friction the area in contact between two objects is comparatively less then that in case of sliding as in rolling, one object just roll over each other hence area of contact is less so force of rolling friction is less than sliding friction.

What are friction forces?
The frictional forces refers to the force that resists the relative motion of the fluid layers and the solid surfaces. It usually resists the given material elements from sliding against each other.
What is the force that static friction can exert on oa object that is moving 15 kilograms west and 25 newtons is being exerted?
"Static friction" refers to objects that are NOT moving.The amount of friction depends on the so-called "coefficient of friction", which varies depending on the properties of the surfaces that are in contact.
Why do you skate faster on ice than on the street?
because ice surface refers very less friction as compare to roads that is why skating is easy on ice surfaces
Why is a football not a polygon?

The term conflict refers to?
Conflict is a term that means some form of disagreement, discord, or friction between different groups or people.
Is CORNER a preposition?
No, "corner" is not a preposition. It is a noun that refers to the point at which two lines or surfaces meet. Examples of prepositions include "on," "in," "under," and "between."
