Mass and Weight

Thermodynamics Directory | Heat Transfer Directory

The mass (m) of a body is the measure of the amount of material present in that body. The weight (wt) of a body is the force exerted by that body when its mass is accelerated in agravitational field. Mass and weight are related as shown in following Equation:

Note that gc has the same numerical value as the acceleration of gravity at sea level, but is notthe acceleration of gravity. Rather, it is a dimensional constant employed to facilitate the use of

Newton’s Second Law of Motion with the English system of units.

The weight of a body is a force produced when the mass of the body is accelerated by agravitational acceleration. The mass of a certain body will remain constant even if thegravitational acceleration acting upon that body changes.
