the frictional forces increase
Friction is an action, frictional force is a force. Typically the static or kinetic friction of an object causes a frictional force when there is an attempt at moving the object, the frictional force is always opposite to the applied force, as it is the force you must overcome to move the object.
kinetic frictional
Use round wheels to roll the load, lighten the weight by removing attached or contained objects, or place a smoother surface betwen the object and the floor. Water or other fluids can be used to decrease the resistance, but only if they remain between the object and the floor.
Say you are moving an object against the carpet flooring, you are the force and you are causing the object to move as well as you are creating friction between the carpet and the object. The force would be called the netforce, which is all the forces that are acting on an object.
the frictional forces increase
Frictional force resists movement. In order to set an object into motion (or accelerate an already moving object), the force of friction must be overcome.

You increase the frictional force by applying the brakes.
Friction is a force that always acts in a direction opposite to that of motion. So the frictional force does negative work on the velocity of an object ( thus reducing the speed of an object).
Static friction. The frictional force is greater then the force applied, meaning the object can't move.
An object has a general tendency to keep moving - that's how our Universe works. No force is required to keep an object moving - unless there is another force that slows it down. Here on Earth, there are usually frictional forces that slow objects down, and therefore a force is required to counteract the frictional forces.
You have three separate situations here:1. Object stays at rest. The force on the object is not great enough to overcome its frictional forces, or its inertia.2. Object keeps moving at constant velocity. The object's inertia and frictional forces are exactly balancedby the Force exerted on it.3. Object moves with increasing velocity (acceleration). The Force on the object exceeds that necessary to overcome its inertia and its frictional forces.
