Friction affects us in everyday living by allowing us to walk, drive, and grip objects. It helps us stop when braking, hold onto objects, and walk without slipping. Friction also generates heat and enables the functioning of machines and devices.
The variable that does not affect friction is the surface area in contact. Friction is primarily influenced by the nature of the surfaces in contact, the applied force, and the roughness of the surfaces. The surface area does not have a direct effect on the frictional force generated between two surfaces.
Friction is the force that opposes motion between two surfaces in contact. It can affect the speed and efficiency of moving objects by creating resistance. Understanding friction allows us to design better systems and materials to minimize its effects and improve performance.
Weight affects friction by increasing the force pressing the surfaces together, resulting in more friction. Mass does not directly affect friction, but it influences the normal force, which in turn affects friction. Generally, higher weight or mass leads to higher friction.
The two variables that affect friction are the surface roughness of the materials in contact and the force pressing the surfaces together. As the roughness increases or the force increases, friction typically increases as well.
friction
We would need to know what the friction is to affect to respond to this question.
ice can affect friction
Speed does not affect the force of friction.
surface friction and sliding friction
Friction will slow it down
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.

the smoother a surface is, the less friction it produces.
The nature of the surface. A measure of this is the coefficient of friction.
As water in the stream channel flows, it encounters friction; the friction slows the forward movement. The shape,size, and roughness affect the amount of friction. High friction slows the stream significantly.
