Measurements

This topic comprises the concept of measurement and the method of measuring with the equipments. We will moreover comprehend its importance and characteristics through visual content and examples discussed here.

In this topic, we will learn how to derive dimensions of the different physical quantities. It also explains certain rules and modes of representation of the dimension of physical quantities.

In this topic, will study the standard form of the unit and its types. It provides the tables that define its importance of measuring with the aid of pictures.

This topic talks about the concept of prefixes of unit. It explains that the metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit.  

This topic discusses the lengths of several objects that we see in our day-to-day lives. It includes an activity to measure the length of each of these objects using handspans.

This topic introduces us to the concept of area. It uses some examples and interesting activities like puzzles and friendly challenges to explain the concepts of calculation as well as the division of any given area.

This topic discusses the volume of objects by taking the examples of a lemon drink, jugs, glasses, bottles and milk for a better understanding for the students.

In this topic, we will learn how to calculate the mass of an object. It explains the method of approach to the questions with the help of solved examples. We will also study that the mass of an object remains constant and does not change from place to place.

In this topic, we will discuss the vision of time. In classical, non-relativistic physics, it is similar to length, mass and charge are usually described as a fundamental quantity. We will also understand that time is a scalar quality.

This topic describes temperature as a physical quantity which expresses hotness and coldness of a body. It briefs on the phenomenon of thermal energy. We will also learn about the instruments used to measure temperature.

This topic discusses the conventions for writing units and their symbols. The names of SI units are written in lowercase, and the symbols of units named after a person are capitalized. These symbols are not abbreviations, so periods are not required.

This topic talks about approximation and estimation. It mentions that estimate is to calculate roughly, often from imperfect data, while approximate is to carry or advance near that lead to cause to approach, demonstrated through examples.

In this topic, we will keep ourselves informed of and study critically about the status of physics. Newly established structures that allow the maintenance of standards, are illustrated through tables and examples.
