A rough surface like sandpaper will have more friction than a smooth surface. smoothing out a surface will reduce friction
Because there are no frictional forces.
opposing the motion
The vector sum of all applied and frictional forces on an object is the net force acting on the object. This net force determines the object's acceleration according to Newton's second law, F = ma, where F is the net force, m is the mass of the object, and a is the acceleration.
forces of body depends on the path it is moving for example if it is moving in straight path it under go forces like frictional forces and forces applied on it if the body is moving in slant path it has frictional force,acceleration due to to gravity(which acts down wards)
Well, the forces that keep it in place are gravity and friction. You pretty much answered the question yourself.
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.
cause motion &+ cause positive acceleration . #
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.
Oppose & Prevent
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!
