The force of friction, which is the normal force (weight) multiplied by the coefficient of friction (how rough the carpet is).
An immovable concrete wall works pretty good for me.Theoretically it is said that Zero Kelvin (absolute zero) is the temperature at which no movement of particles/molecules is possible. Zero Kelvin in Celsius is -273.15 degrees. In Fahrenheit it is -459.67 degrees.
There may not be enough friction between your feet and the floor. You need friction to be able to exert a force against the floor, to balance yourself and move in the direction you desire.
which following is an exmpale of the force of friction
The normal force between the two objects and the coefficient of friction. Force of friction = normal force x coefficient of friction.
Friction is considered a force because it acts on an item and causes changes, which is what a force is. Nothing would happen if the item was in an area where friction was not possible or if friction was where an object was not since they need each other to exert external effort.

Statical friction
There may not be enough friction between your feet and the floor. You need friction to be able to exert a force against the floor, to balance yourself and move in the direction you desire.
friction is a natural force
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
Friction requires that forces be greater to move an object, but friction also makes it possible for an object to stop moving without an external applied force. Remember, friction ALWAYS opposes motion.
which following is an exmpale of the force of friction
No. Friction can only slow an object down. If friction were imparting a force greater than that of the applied forces, then friction in and of itself would actually be causing the object to move, which does not happen.
The normal force between the two objects and the coefficient of friction. Force of friction = normal force x coefficient of friction.
