Friction affects the world a lot. With out friction, we would have no grip. We will continuously slide. Nothing will stay still - unless stopped by a wall.
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.
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.
The two types of friction that affect a mousetrap car are rolling friction, which occurs between the wheels and the surface of the ground, and sliding friction, which occurs between the axles and the wheels. Both types of friction can reduce the overall efficiency and speed of the mousetrap car.
Yes, machines in the real world lose energy due to friction. Friction causes resistance, which leads to heat generation and energy loss. This energy loss can affect the efficiency and performance of machines.
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 nature of the surface. A measure of this is the coefficient of friction.
the smoother a surface is, the less friction it produces.

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.
