Does friction act at a distance?
No, friction is a force that acts between two surfaces that are in contact with each other. It is a result of microscopic interactions at the surfaces of the objects in contact.
Does friction act upon water?
Friction does act upon water, although it is generally less noticeable compared to solid surfaces due to water's lower viscosity. When water flows past a solid surface, or when water molecules slide past one another, frictional forces are present and contribute to the overall movement or resistance within the water.
What needed in order for friction to happen?
Friction occurs when two surfaces come into contact with each other and there is a force acting between them. This force can be caused by the roughness of the surfaces, adhesion between them, or deformation of the materials. Additionally, motion or the attempt at motion between the surfaces is necessary for friction to act.
Does friction act perpendicular or parallel to the surfaces in contact?
Parallel, surfaces are never perfect, and the peaks and valleys along these surfaces are the objects that interact to create resistance to movement parallel to the surfaces.
How does friction act on an object?
Friction acts as a force that opposes the motion of an object when it is in contact with another surface. It occurs because of the roughness of surfaces interacting at a microscopic level. The amount of friction depends on the roughness of the surfaces and the force pressing them together.

Why lubricant is used when metal parts rub together?
These substances are caused to insinuate themselves between the surfaces, and have the property of so separating them as to prevent serious abrasion. The solid and semi-solid lubricants seem to act as rollers between the surfaces, or form a film between them which itself suffers abrasion or friction. The liquid lubricants, however, maintain themselves as liquid films between the surfaces, upon which the bearing floats

What is a force that opposes motion between two surfaces that are touching is called?
Friction and inertia's factors
When friction is greater when surface have more is it gravity or roughness?
Both. Suppose you want to move something over the ground. If it becomes heavier then it will be subject to more friction on account of gravity. If it's lower surface becomes rougher then again, it will be subject to more friction. The force pressing two surfaces together and the roughness of the two surfaces act together to produce friction.
Why the friction between two surfaces increases when they are pressed harder?
When two surfaces are pressed harder together, the microscopic irregularities on the surfaces come into closer contact. This leads to more contact points where frictional forces can act, increasing the overall friction between the surfaces. Additionally, the increase in force can cause intermolecular interactions to become stronger, further enhancing the friction between the surfaces.
Is friction a force that acts when two surfaces rub together?
Yes, friction is a force that opposes the motion of objects when two surfaces come in contact and rub against each other. It can act to slow down or stop the movement of objects due to the resistance generated between the surfaces.
What is different between static friction and kinetic friction?
Between any two body surfaces in contact there acts an frictional force. A friction can operate between a given pair of solids, between a solid and fluid or between a pair of fluids. There are two types of frictional forces : kinetic and static friction. When two bodies in contact move with respect to each other , rubbing the surfaces in contact the friction between them is called kinetic friction. The directions of frictional forces are such that it opposes the relative motion. Friction forces can also act between two bodies which are in contact but not moving or sliding with respect to each other. The friction in such case is static friction.
What are the principles of friction?
Friction is caused by the interaction of two surfaces in contact. The frictional force opposes the motion of an object or resists the force applied on it. Frictional force is dependent on the nature of the surfaces and the normal force pressing them together.
