It also tells them about the international system of units, commonly known as the SI System.<\/p>\n<p>There are two distinct types of quantities, namely, base quantities and physical quantities. Base quantities are a standard of reference for physical quantities. Their measurements are arbitrary and depend on the SI or international system of units. The SI system of units is a widely accepted format to measure both the base and physical quantities.<\/p>\n<p>According to this system, there are seven fundamental units used to measure all the quantities. While the base quantities have a set unit of measurement, the units of physical quantities come from the base quantities themselves. The international system of units also defines symbols for measuring each quantity.<\/p>\n<p>For example, \u2018kilogram,\u2019 the unit of measurement for weight has the symbol, \u2018kg.\u2019 Similarly, the unit of measure for any liquid, that is, \u2018liter,\u2019 is expressed using the letter \u2018l.\u2019<\/p>\n<p>The chapter also tells about the methods in which you can derive the units of measurement for each quantity using equations. Such equations originate from a technique called \u2018dimensional analysis.\u2019 The dimensional analysis technique also checks for inconsistencies in the equations. Thus, a dimensionally consistent equation need not always be correct. However, dimensional inconsistencies in equations mean that they are inaccurate.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"topics-covered-in-class-11-chapter-2-physics-units-and-measurement\"><\/span>Topics covered in Class 11 Chapter 2 Physics Units and Measurement<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div>\n<table>\n<tbody>\n<tr>\n<td><strong>Section Number<\/strong><\/td>\n<td><strong>Topic<\/strong><\/td>\n<\/tr>\n<tr>\n<td>2.1<\/td>\n<td>Introduction<\/td>\n<\/tr>\n<tr>\n<td>2.2<\/td>\n<td>The International System Of Units<\/td>\n<\/tr>\n<tr>\n<td>2.3<\/td>\n<td>Measurement Of Length<\/td>\n<\/tr>\n<tr>\n<td>2.4<\/td>\n<td>Measurement Of Mass<\/td>\n<\/tr>\n<tr>\n<td>2.5<\/td>\n<td>Measurement Of Time<\/td>\n<\/tr>\n<tr>\n<td>2.6<\/td>\n<td>Accuracy, Precision Of Instruments And Errors In Measurement<\/td>\n<\/tr>\n<tr>\n<td>2.7<\/td>\n<td>Significant Figures<\/td>\n<\/tr>\n<tr>\n<td>2.8<\/td>\n<td>Dimensions Of Physical Quantities<\/td>\n<\/tr>\n<tr>\n<td>2.9<\/td>\n<td>Dimensional Formulae And Dimensional Equations<\/td>\n<\/tr>\n<tr>\n<td>2.10<\/td>\n<td>Dimensional Analysis And Its Applications<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h3><span class=\"ez-toc-section\" id=\"theorems-and-formulae\"><\/span>Theorems and Formulae<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The chapter makes use of various formulae to explain the concepts. The most common ones include that of speed, distance, and time, as well as the density of different substances. Here, you can find the formulae used for both these quantities along with their units of measurement.<\/p>\n<p>We know that,<\/p>\n<p>Speed = Distance\/Time.<\/p>\n<p>So, from this, we can infer that,<\/p>\n<p>Time = Distance\/Speed<\/p>\n<p>Or<\/p>\n<p>Distance = Speed * Time.<\/p>\n<p>We also know that time and distance are fundamental quantities having second and kilometer or meter as their units. So, from this, we can derive the unit of the physical quantity, speed, which is as follows.<\/p>\n<p>Since,<\/p>\n<p>Speed = Distance\/Time, we get,<\/p>\n<p>Distance\/Time = meter\/second = Speed.<\/p>\n<p>Thus, we come to know that the unit of measurement for speed is meter per second or m\/s.<\/p>\n<p>Similarly, we have the formula for measuring the density of a substance, given by,<\/p>\n<p>Relative Density = Density of Substance\/Density of Water.<\/p>\n<p>From this, we infer that,<\/p>\n<p>Density of Substance = Relative Density * Density of Water.<\/p>\n<p>So, in this way, the chapter explains the different base and physical quantities and their units of measurement.
