So, what is normal force? Simply put, it's the force exerted by a surface on an object that is in contact with it. This force is perpendicular to the surface and opposes the weight of the object. Think of it like this: when you stand on the ground, the ground exerts a normal force on your feet, keeping you upright. This force is essential for maintaining balance and stability.

In physics, normal force is often represented by the symbol FN. It's an essential component of Newton's second law of motion, which describes how forces affect the motion of objects. Understanding normal force is crucial for predicting how objects will behave in various situations, from everyday experiences to complex engineering applications.

Normal force and friction are often confused with each other, but they're not the same. Normal force is the force exerted by a surface on an object, while friction is the force that opposes motion between two surfaces in contact. Think of normal force as the "push" of the surface, while friction is the "drag" that slows down motion.

Normal force and gravity are related but distinct forces. Gravity is the force that pulls objects towards each other, while normal force is the force exerted by a surface on an object. When an object is standing on a surface, the normal force opposes the weight of the object, which is the force due to gravity.

Not always. Normal force can be greater than or less than the weight of the object, depending on the surface's properties and the object's mass.
