friction
There is usually less friction from a smooth plastic mat than between clothing and the slide, but it depends on the material. Most dry cotton fabrics will slide fairly easily.On *water slides* these mats are used because bare skin will not slide very smoothly compared to non-porous materials.
The downward force of gravity, and the normal force perpendicular to the slide.
The causes of the resistive force of friction are1.molecular adhesion2.surface roughness3.the plowing effect.Adhesion is the molecular force resulting when two materials are brought into close contact with each other. Trying to slide objects against each other requires breaking these adhesive bonds. For years, scientists thought that friction was caused by surface roughness, but recent studies have shown that it is actually a result of adhesive forces between the materials.But surface roughness is a factor when the materials are rough enough to cause serious abrasion. This is called the sandpaper effect.When one or more of the materials is relatively soft, much of the resistance to movement is caused by deformations of the objects or by a plowing effect.
The particles in a liquid have a weak force between them. They are still close together like the particles in a solid, just more loosely connected. They can freely move and slide past each other. =)
rock materials (debris) and other loose materials suddenly move downhill as a whole without breaking up and unlike slump there is no back-tilting of the mass.
What provides light to allow you to view materials on a glass slide
Friction i do believe

Most inflatable water slide toys are made of polyvinyl chloride (PVC). There are other materials that are used to make inflatable water slide toys as well.
1. The forces involved are arise in response to the action of an applied force. 2. Discuss the interaction between an object and a surface it is resting on; the object pushes down on the surface; the surface pushes up on the object with an equal force; this is called the reaction of the surface. 3. Discuss the interaction between two surfaces which slide (or tend to slide) relative to each other; each surface experiences a force in the direction which prevents (or tends to prevent) relative movement; this interaction is called friction.
