This document provides an introduction to measurements and physical quantities. It defines a physical quantity as a property of a material or system that can be quantified by measurement. Physical quantities have a numerical value and unit, such as 10 kg for a block's mass or 5 km for the distance to a school. Some common physical quantities are listed as time, mass, length, temperature, electricity, charge, work, force, weight, energy, power, frequency, velocity, and density. The document concludes by assigning homework for students to further study the physical quantities of mass, temperature, time, and length.
