Frictional forces include static friction (preventing movement), kinetic friction (opposing motion), rolling friction (resistance between rolling surfaces), and fluid friction (resistance in fluids). These forces arise from the interaction between two surfaces in contact and can vary based on factors such as surface roughness and the nature of the materials involved.
Mechanical, gravitational, electrical, magnetic, frictional, and tension forces can do work. These forces can cause an object to move over a distance and transfer energy to or from the object in the process.
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.
When a car is moving in the forward direction, the main forces at play are the engine force propelling the car forward, the frictional force between the tires and the road providing traction, and air resistance acting against the car's motion. These forces work together to keep the car moving in the desired direction.

Most forces other than frictional force can be converted into other kinds of force.

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.
