No, the frictional force does not depend on the area of surface contact. It is primarily determined by the nature of the surfaces in contact and the normal force pressing the surfaces together. The coefficient of friction between the surfaces also plays a role in determining the magnitude of the frictional force.
Frictional force is the force that opposes motion between two surfaces.
Frictional force depends on the nature of the surfaces in contact and the force pressing them together.
The magnitude of frictional force depends on the nature of the surfaces in contact and the normal force pressing the surfaces together.
The contact area hardly affects the frictional force. The frictional force depends on the normal force, and the coefficient of friction, which is a property you have to look up (or measure) for every pair of materials.

Frictional force depends on the nature of the surfaces in contact and can vary based on surface roughness, temperature, and the presence of lubricants. It does not depend on the surface area in contact but relies on the normal force acting between the surfaces. Frictional force can also generate heat and wear on the surfaces in contact, leading to energy loss and decreased efficiency in mechanical systems.

Frictional force depends on the contact force and on the coefficient of friction. The coefficient of friction depends on the types of materials in contact; the contact force may depend on mass, if it is caused by gravity.
The two factors that determine frictional force are the roughness of the surfaces in contact and the amount of force pressing the surfaces together. Rougher surfaces and greater contact force result in higher frictional force.
The frictional force between an object and a surface is independent of the velocity of the object. It is primarily determined by the nature of the surfaces in contact and the normal force acting between them. However, at very high velocities, dynamic friction can increase due to factors like heat generation.
oppose the motion of an object in contact with a surface. It is dependent on the nature of the surfaces in contact and the normal force pressing them together.
If the surface is smooth then it is almost frictionless. Hence the body will continue to move with constant velocity. However the object continues in a circular path and the weight is thus the centripetal force. It is assumed that the surface is very large)
