Compare/contrast the physically measured quantities of mass and weight

Homework Answers

Answer #1

Mass:

Mass is the measure of the amount of matter in a body. Mass is denoted using m or M.

Mass is a property of matter. The mass of an object is the same everywhere and it can never be zero. Mass is a scalar quantity. It has magnitude. SI unit is Kg.

Weight:

Weight is the measure of the amount of force acting on a mass due to the acceleration due to gravity.

W = m * g

Weight usually is denoted by W. Weight is mass multiplied by the acceleration of gravity. Weight depends on the effect of gravity. Weight varies according to location. Weight can be zero if no gravity acts upon an object, as in space. Weight is a vector quantity. It has magnitude and is directed toward the center of the Earth or other gravity well. SI unit is Newton.
