Final answer:
The normal force, FN, can change based on the interactions between the object and its environment, such as the angle of the surface or additional forces applied to the object.The normal force, FN, applied by an object can change depending on the situation. It is not always the same value.
Step-by-step explanation:
The normal force, FN, applied by an object can change depending on the situation. The normal force is the force exerted by a surface to support the weight of an object resting on it. It always acts perpendicular to the surface.
For example, if an object is placed on a horizontal surface and there are no other forces acting on it, the normal force will be equal in magnitude and opposite in direction to the weight of the object. However, if an object is placed on an inclined plane, the normal force will be less than the weight of the object due to the presence of the gravitational force component acting along the incline.
Therefore, the value of the normal force, FN, can vary depending on the specific conditions of the object and the surface it is interacting with.
