Question

Answer 1

Mass is constant.
Weight varies from place to place.

Mass does not depend on Gravity
Weight depends.

Answer 2

Mass - 1) Mass is a scalar quantity. It has only magnitude.
2) Mass is a property of matter. The mass of an object is the same everywhere,
3) Mass can never be zero.
4) Mass usually is measured in grams and kilograms.

Weight - 1) Weight is a vector quantity. It has magnitude and is directed toward the center of the Earth or other gravity well.
2) Weight depends on the effect of gravity. Weight varies according to location.
3) Weight can be zero if no gravity acts upon an object, as in space.
4) Weight often is measured in newtons, a unit of force.
