Practice Other Topics from Units and Measurements
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.
This topic explains the international system of units. It also discusses the base units for length, mass and time in CGS, MKS and the FPS system along with their SI units.
In this topic, students are asked to measure objects with the help of a scale. They are taught the conversion values between units of measurements namely, millimetre, centimetre and metre. Colouring, guess and draw activities make the topic interesting.
This topic explains about the notion of measuring mass and its respective standards. We will also get an idea about the range and order of masses for a vast array of objects, such as microscopic particles, human beings, and astronomical objects.
In this topic, we will study how to measure any time interval. It also explains the use of cesium in the atomic clock to measure the time. SI unit of time and the department responsible for the maintenance and improvement of physical standards in India are also discussed.
In this topic, we will learn the accuracy and precision of instruments while measuring the different quantities. It also gives examples based on the concept for a better understanding.
In this topic, we will learn about the classification of error in measurement. We will also learn about accuracy and precision.
In this topic, we will learn about significant figures. We will learn the rules for arithmetic operations with significant figures and for determining the uncertainty in the results of arithmetic calculations.
In this topic, we will understand the equation obtained by equating a physical quantity with its dimensional formula. The different dimensional equation is also explained here in detail.
In this topic, we will analyse the dimensional formulas and learn its applications. It also describes the principle of homogeneity of dimensions. We will also learn to deduce relations among the physical quantities.
