Slopes have the same friction of the road but in slopes the Potential energy changes into Kinetic Energy which causes movement..

Different slopes can affect friction by changing the normal force acting on an object. On steeper slopes, the normal force decreases, which reduces the friction force holding the object in place. This can make it easier for the object to slide or move.
The force that keeps a box from sliding down an angled conveyor belt that slopes upward is friction. Friction acts in the opposite direction of the box's movement, preventing it from sliding down the slope.
Some common questions about friction that are frequently asked include: What is friction and how does it work? What factors affect the amount of friction between two surfaces? How can friction be reduced or increased? What are the different types of friction?
The type of material affects friction because different materials have different surface textures and properties that can either increase or decrease the amount of friction between two surfaces in contact. Rougher materials typically create more friction, while smoother materials create less friction.
Changing the type of surface area can affect sliding friction because different materials have different levels of smoothness and roughness. A smoother surface will typically have less sliding friction as there is less resistance between the two surfaces. In contrast, a rougher surface will create more friction due to increased contact points and resistance.
The two factors that affect the amount of friction between two objects are the types of materials and the force pressing the surfaces together. Different materials have different levels of roughness, which can affect the amount of friction. The force pressing the surfaces together determines how tightly the two objects are in contact, leading to variations in the frictional force between them.
