In Physics, "normal" force means force that's perpendicular to something, usually to a surface.
In that usage, 'normal' does not mean ordinary, typical, usual, familiar, etc.
Perpendicular to the surface.
Normal force is the component perpendicular to the surface in mechanics. It prevents an object from penetrating the surface with the contact force exerted.
tension(Associated with Normal faults)
The support force on an object is called the normal force because it is a force "normal" to the object. "Normal" in this sense means perpendicular.
-- The friction force changes, and is directly proportional to the normal force. -- The coefficient of friction doesn't change. It is the proportionality constant in the first statement.
the force that a solid surface exerts on any object in normal direction is called the normal force
tensional forces

tension(Associated with Normal faults)
The support force on an object is called the normal force because it is a force "normal" to the object. "Normal" in this sense means perpendicular.
This type of problems about friction are extremely simple: You just multiply the normal force by the coefficient of friction to get the frictional force.
-- The friction force changes, and is directly proportional to the normal force. -- The coefficient of friction doesn't change. It is the proportionality constant in the first statement.
There are at least four types of forces in physics. They include applied force, gravitational force, normal force, and frictional force. Other types of force can also include spring force, tension force, and air resistance force.
Normal force can act on an object
Normal Force- this is the support force exerted on an object in contact with another stable object.
the force that a solid surface exerts on any object in normal direction is called the normal force
