Up to this point in the course we have treated everything as a single point in space, no matter the mass, size, or shape. We call this “special point” the . CENTER OF MASS. . The . CoM. is basically a coordinate which represents the average position of the mass..

Mass. is the measure of the amount of matter in an object.. Mass and Weight are different. . Weight. is the amount of gravitational force pulling on an object. . Weight can also change from place to place (planet to planet), but mass always stays the same..

Atomic Mass. What is an elements atomic mass?. The weighted average of its naturally occurring isotopes. .. When looking at an element on the periodic table of elements, where is atomic mass found?. Usually the top left hand corner of each elements box. However, on the periodic table that you will use for your AP Exam(s), this number will be located below each elements chemical symbol..
