Vector quantities have both magnitude and an associated direction. This makes them different from scalar quantities, which just have magnitude.
The gravitational field on Earth varies not only with latitude, but also with altitude and in other ways, particularly due to crustal thickness and the fact that the Earth's crust effectively floats ...
