Normal Force Formula: Concept, Derivation, Sample Questions

In the case of an object resting upon a flat table (unlike on an incline as in Figures 1 and 2), the normal force on the object is equal but in opposite direction to the gravitational force applied on the object (or the weight of the object), that is, $${\displaystyle F_{n}=mg}$$, where m is mass, and g is the … Ver mais In mechanics, the normal force $${\displaystyle F_{n}}$$ is the component of a contact force that is perpendicular to the surface that an object contacts, as in Figure 1. In this instance normal is used in the Ver mais Normal force is directly a result of Pauli exclusion principle and not a true force per se: it is a result of the interactions of the electrons at the surfaces of the objects.
