Center of Mass - GSU

WebMass is a measurement of how much matter is in an object. Mass is a combination of the total number of atoms, the density of the atoms, and the type of atoms in an object. How to Measure Mass Mass is usually measured in kilograms which is abbreviated as kg. In physics there are different ways of determining the quantity of mass. WebA squash ball of mass 25 g is moving from left to right at 3.2 ms-1.
