I want to know why
Static friction∝normal reaction and
Why not
Static friction∝ area of surface
Static friction∝weight
Static friction∝normal reaction and
Why not
Static friction∝ area of surface
Static friction∝weight

The normal force can be a function of the object's weight, but not necessarily as a direct proportionality function. Also there may be other forces acting on the object other than just the weight of the object.akashpandey said:Static friction∝weight
Static friction is the force that resists the relative motion or tendency of motion between two surfaces that are in contact with each other. It is a type of friction that occurs when there is no relative motion between the surfaces.
Static friction is directly proportional to normal reaction because the force of static friction is dependent on the force pushing the two surfaces together, which is the normal reaction force. As the normal reaction force increases, the force of static friction also increases.
The coefficient of static friction is a constant value that represents the roughness or smoothness of the surfaces in contact. It is directly proportional to the normal reaction force, meaning that as the normal reaction force increases, the coefficient of static friction also increases.
No, static friction cannot be greater than the normal reaction force. This is because the force of static friction is limited by the maximum value of the coefficient of static friction and the normal reaction force. If the applied force exceeds the maximum value of static friction, the object will start to move and the force of kinetic friction will take over.
The angle of inclination does not directly affect the force of static friction. However, if the angle of inclination is greater than the angle of friction (the angle at which an object starts to slide), then the object will start to move and the force of kinetic friction will take over. Therefore, the angle of inclination indirectly affects the force of friction by determining whether static or kinetic friction will be present.
