Yes, because without it, we couldn't walk. Walking is using the friction on the ground to hold our foot in one place as we lunge forward, so if it weren't for friction, then our foot would slip and we wouldn't be able to go anywhere.

Does the nature in contact influence friction force?
Since friction means a contact force, the nature of contact will influence friction force. Smoothness of objects affect the friction force. However, as contact pressure rises, the friction does not rise.
What properties affect the force of friction?
The nature of the surface. A measure of this is the coefficient of friction.
What is the mathematical equation for friction?
An important formula is that friction = (coefficient of friction) x (normal force).
Why is friction an important force?
friction is an important force to have in life because friction helps objects that move or roll stop. Like brakes on a car, when you push down on the brakes the friction is there when the wheels stop,and the car will stop to.
What is the main force in nature that causes water to flow?
Is it momentum friction electricity or gravity
What is the force when two materials rub together?
The force when two materials rub together is called friction. Friction is a resistive force that opposes the relative motion or tendency of motion between two surfaces in contact. The magnitude of the frictional force depends on factors such as the nature of the surfaces and the force pressing them together.
Static friction is a self adjusting force explain?
i think that static friction is the friction onl because of mass and nature of the surface
Does the nature of surface in contact influence friction force?
Yes. Roughly speaking, smooth surfaces tend to have less frictional force.
The ratio of the resistance force to the effort force is called?
The ratio of resistance force to effort force is a mechanical advantage.
Unbalanced force opposing motion between touching surfaces?
The unbalanced force that opposes motion between touching surfaces is called friction. It acts in the opposite direction of the applied force and depends on the nature of the surfaces and the force pressing them together. Friction can be reduced by using lubricants or by increasing the smoothness of the surfaces.
On what factors do the fluid friction depends?
the force of friction in a fluid depends on it's speed with respect to the fluid. It also depends on the shape of the object and the nature of the fluid.
Which force slows down a ball when it moves?
The force of friction, which is the normal force (weight) multiplied by the coefficient of friction (how rough the carpet is).
