Weight is the force of attraction due to the Earth pulling us. This is due to gravity.  Fortunately, we do not go up.  The pull of the earth is always directed to the center of the earth.  Our mass , the total quantity of the matter in our body does not change, and there is no specific direction associated with this dimension.

Physical quantities that have both magnitude and direction are known as Vectors. Scalar quantity are those that only have magnitude and no directions.
