Finding Mass Using the Inertial Balance Theory: Physics can be referred to as the study of various properties of matter and energy. Matter can best be described by looking at the mass of an object. Mass is the amount of material that is in an object. Mass can be found by using a spring scale, a balance scale, or an inertial balance. Inertia is the resistance by mass to any change in its state of motion. Scientific Law states that mass and inertial forces are directly proportional. The purpose of the inertial balance is to measure the different inertias between different masses therefore providing a mathematical and very accurate method of measuring mass. Exper
