false
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.
false. Kinetic friction is the friction acting upon a moving object. It would be the frictional force against you if you pulled a box across a table. Static friction is the frictional force needed to overcome to get an object at rest into motion.
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.
Friction definitely is a force that can make things easier. Stopping a car for example is made easier by friction.

true. Friction DOES slow things down. In fact, if there was no friction once something started moving it wouldn't be able to stop Friction can slow the things down. It's true.
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.

No, friction is a force which always acts in the direction opposite to that of motion.
