)Normal force equilibrium is a state in which an object is at rest or moving at a constant velocity, with the sum of all normal forces acting on the object equal to zero. This means that the forces acting perpendicular to the surface of the object are balanced, resulting in no net force.
Normal force equilibrium is specific to objects that are in contact with a surface. Other types of equilibrium, such as static and dynamic equilibrium, also take into account forces acting parallel to the surface of an object.
Normal force equilibrium can be affected by the weight of an object, the angle at which it is placed on a surface, and any external forces acting on the object.
Normal force equilibrium is used in many everyday situations, such as balancing objects on a table or shelf, determining the weight distribution of a building on its foundation, and understanding the forces acting on an object on an incline.
If normal force equilibrium is not achieved, the object will experience a net force and will either accelerate or decelerate. This can result in the object sliding or tipping over, depending on the direction of the net force.
