It's not. For there to be friction, there must be nodistance between the objects (surfaces) in question. Action at a distance forces are forces like gravity and electromagnetism. These forces can affect the state of an object with no media attached to the object.

What is frictional resistance due to motion through air?
This frictional resistance known as "air resistance" is the drag force. The drag force changes with the drag coefficient of the object in motion.
What is a turning force?
The turning effects of forces are known as moments. A moment is computed by multiplying the force by the perpendicular distance from its line of action to the fulcrum.
What is applying a force through a distance known as?
We do work when we apply a force through a distance.
What is the name of the force that always acts against the direction of movement?
In geneal frictional force. If it rubs against a surface then it is known to be friction. If it drags the moving body then it is said to be viscous drag.
Define moment and moment of a force?
A moment, also known as torque, is a measure of the tendency of a force to cause an object to rotate around an axis or point. It is calculated by multiplying the magnitude of the force by the perpendicular distance from the line of action of the force to the axis of rotation. The moment of a force is the product of the force and the perpendicular distance from the point of rotation to the line of action of the force. It is a vector quantity that describes how much a force tends to make an object rotate. Moments are important in physics and engineering for understanding the effects of forces on objects and structures.
Applying a force through a distance known as?
work
What is applying a force through distance is know as?
Applying a force through a distance is known as work. Work equals force in Newtons times distance in meters, and the unit for force is the Newton•meter, N•m.
What is the dimension of moments of force?
Moment of force, also known as torque, has dimensions of force x distance.
What is gravitional force reduced by?
Gravitational force depends on the masses involved, and on the distance. There is no known way to "block" the gravitational force.
What 2 things does the moment of a force depend on?
What two factors must be known in order to calculate the moment of a force? Torque = Force * distance Torque and distance must be perpendicular to each other If not you must determine the portion of the torque that is perpendicular.
Why are first and second class levers known as force multipliers?
if the distance is 5
How do mass and distance effect gravitational force?
The gravitational force is equal to mass1 x mass2 / (the square of the distance); all this must be multiplied with a constant, known as the gravitational constant.
