Scalars and Vectors. A scalar is a number which expresses quantity. Scalars may or may not have units associated with them. Examples: mass, volume, energy. Scalars and Vectors. Preliminaries. Many physics variables use the real- number system to pro- vide a quantitative description. Temperature is one such. SCALARS AND VECTORS. Introduction: Physics is the study of natural phenomena. The study of any natural phenomenon involves measurements.

YourDictionary definition and usage example. For instance, the measurement of speed in miles or kilometers-per-hour or the measurement of the temperature of the medium both remain scalar quantities as long as they aren't associated with the direction of the medium's travel. Speed and temperature - Two more commonly used scalar quantities in physical calculations are speed and temperature. Examples of Vector and Scalar Quantity in Physics By YourDictionary In the study of physics, there are many different aspects to measure and many types of measurement tools. Velocity - The measurement of the rate at which an object changes position is a vector quantity.
