The main characteristic is the heat between particles! , they rubbed against each other to hold the object in position.
causes of friction are strength and direction

Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
Objects which cause little amount of friction are smooth objects such as glass and other objects which are man-made (most of the time). However, there are many objects which are natural which can create minimal amounts of friction too.answ2. Very often, using two different materials will give superior wear characteristics - = low friction. e.g. White metal bearings against steel, Steel against wood (in ship's prop shafts).I'd expect glass against glass to have a high friction coefficient.
Lubricants reduce friction by replacing sliding friction with fluid friction.
Friction is reduced on a wet floor.
The heat from the friction upon two objects.

a liquid that is able to reduce friction plus it can be recycled and it is also a fossil fuel byproduct

Similar properties to engine oils but different friction characteristics. They have to withstand high pressures and temperatures.
The energy lost through friction as a fluid flows through a pipe. The amount of energy lost is dependent on both the characteristics of the fluid (viscosity, density) and the pipe (roughness, diameter, length) as well as the rate of flow.
Frictional interaction is the frictional force that influence and are influenced by the response of dynamic system from which they are generated and this interaction continuously changes the contact characteristics at the interface.
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
Friction always acts in a direction opposite to the direction of motion. When to push or pull an object, friction manifests in a direction opposite to motion and the frictional force is dependent on the characteristics of the surfaces. When the push or pull force is slowly increased, at a certain point the frictional force is overcome and the object starts moving.
Objects which cause little amount of friction are smooth objects such as glass and other objects which are man-made (most of the time).

i think it it rolling friction
