Friction definitely is a force that can make things easier. Stopping a car for example is made easier by friction.

== == AnswersIt is easier to stop sliding friction than rolling friction. The force due to sliding friction will always be greater than the force due to rolling friction. And since friction force will be in the opposite direction of motion it will be easier to stop an object in motion that is sliding than one that is rolling.
from ChaCha answersIncreasing the force of scrubbing increases the friction between the scrub brush and the pot, and so cleans it better.
There is no force opposite to friction. In fact, friction is not actually a force, although we treat it as if it were one, in order to make the math and physics easier. The concept of a force opposite to friction might be 'lubricity' ... the ability of two surfaces to slide past each other. The opposite force of friction depends on all the other forces applied to any moving object, since those determine the object's motion, and friction always acts in the direction exactly opposite to the object's motion.

Wheels make movement easier because they roll and their round and the friction helps to move more easier.

Friction itself is a naturally occurring force but yes, tectonic plates do encounter friction.
Increase the normal force, or push down on it more (add more weight). friction = μ normal force μ is the coefficient of friction which is different for different surfaces
It can make moving heavy objects easier for example sliding friction you can slide it or rolling friction you can roll the object across some kind of round cylinders or even fluid friction with water running under the object can make it easier.
The force of friction, which is the normal force (weight) multiplied by the coefficient of friction (how rough the carpet is).
No, friction is a force which always acts in the direction opposite to that of motion.
