Some standard textbooks 41 define weight as a vector quantity, the gravitational force acting on the object. Others 51161 define weight as a scalar quantity, the magnitude of the gravitational force. Yet others! define it as the magnitude of the reaction force exerted on a body by mechanisms that counteract the effects of gravity: the weight is the quantity that is measured by, for example, a spring scale.
