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.
Most forces other than frictional force can be converted into other kinds of force.
Frictional force
Reducing surface roughness, applying lubricants, and using ball bearings can help reduce frictional forces between surfaces.
The size of the frictional force is influenced by the types of materials in contact and the force pressing the materials together. Smoother surfaces and greater forces typically result in larger frictional forces.

Many other forces can change the shape or motion of an object, while frictional forces primarily oppose motion by creating resistance. Additionally, other forces such as gravitational, electromagnetic, and nuclear forces can act over larger distances compared to the localized effects of friction. Frictional forces also do not have the ability to attract or repel objects like electromagnetic forces do.

Because there are no frictional forces.
The frictional force vs normal force graph shows that there is a linear relationship between the two forces. As the normal force increases, the frictional force also increases proportionally. This indicates that the frictional force is directly proportional to the normal force.
Lubricants such as oil or grease can reduce frictional forces by providing a slippery layer between moving surfaces. Polishing or smoothing the surfaces in contact can also reduce frictional forces by eliminating roughness that causes resistance.
A static force is a frictional force between two forces!
A Static force is a force that is frictional, and pulls two things together.
