Yes, the frictional force can increase with an inclined plane, but it depends on several factors including the angle of the incline and the materials in contact.
As an object moves on an incline, the gravitational force acting on it can be resolved into two components: one perpendicular to the surface (normal force) and one parallel to the surface (which involves sliding down the incline). The frictional force is primarily influenced by the normal force, which decreases as the incline angle increases. Since friction is a product of the normal force and the coefficient of friction between the surfaces, if the angle increases too much, the normal force decreases, resulting in less friction.
However, if the incline is gradual, the frictional force may still be significant enough to oppose the motion of the object. Ultimately, while the frictional force can change as the incline angle changes, it does not simply increase with the incline plane; it is affected by both the angle and the nature of the surfaces in contact.
