Question

What are the advantages of normal force [urgent ,answer plzzz, will mark in brainliest]

Answer 1

it just acts as force to balance the gravitational force so that the object does not get inside the surfaceIn mechanics, the normal force {\displaystyle F_{n}\ } is the component, perpendicular to the surface (surface being a plane) of contact, of the contact force exerted on an object by, for example, the surface of a floor or wall, preventing the object from falling. Here normal refers to the geometry terminology for being perpendicular, as opposed the common language use of normal meaning common or expected. For example, consider a person standing still on the ground, in which case the ground reaction force reduces to the normal force. In another common situation, if an object hits a surface with some speed, and the surface can withstand it, the normal force provides for a rapid deceleration, which will depend on the flexibility of the surface.
