Mass and Weight

Deffinition

Mass           : The auantitiy if matter in an object

Weigth        : The force upon an object due to gravity

Unit

Mass           : Kg

Weight        : Newton in Metric

                    Pounds in British System

Tool to Measure

Mass           : Beam balance or liver balance

Weight        : Spring balance

Value

Mass           : Constant

Weight        : Can change depend on acceleration of gravity

Weight and Mass

·        the moon gravity is 1/6 of earth

·        in the space you’re weigth less not mass less

·        your mass doesn’t depend on where

·        the acceleration gravity is pull force from the earth

·        the acceleration of gravity depend on the position from the center of the earth if the location near the earth, the gravity force will bigger
