    In science and engineering, the weight of an object, is the force acting on the object due to acceleration of gravity. [1][2][3] Some standard textbooks [4] define weight as a vector quantity, the gravitational force acting on the object. Others [5][6] define weight as a scalar quantity, the magnitude of the gravitational force.
