Massis a measurement of an object's tendency to resist changing its state of motion, known as inertia.
<u>Weight</u>, on the other hand, is a measure of the amount of downwards force that gravity exerts on an object. This force increases with the object's mass: the more inertia it has, the harder gravity pulls.
<u>MASS </u>—<em>A</em><em> coherent, typically large body of matter with no definite shape.</em>
<u>WEIGHT</u><u> </u><u>—</u><u> </u><em>A</em><em> body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.</em>
