for example, a book is at rest on a table.
One might say that the normal force is the reaction force.
BUt reaction forces always have to be equal in magnitude, and you put an object on the book, then the normal force would increase to keep the book at rest, therefore the normal force is not the reaction force to gravity because it doesn't have to be equal in magnitude to it.
So what would be the reaction force to gravity?
