Document Content and Description Below

Fundamental Dimensions Physics is a science based upon exact measurement of physical quantities that are dependent upon three fundamental dimensions. The three fundamental or primary dimensions are ... mass, length, and time. These three fundamental units must be understood in order to lay the foundation for the many concepts and principles presented in this material. Mass Mass is the amount of material present in an object. This measurement describes "how much" material makes up an object. Often, mass and weight are confused as being the same because the units used to describe them are similar. Weight (a derived unit, not a fundamental unit) is a measurement that describes the force of gravity on the "mass" of an objec [Show More]
