The second chapter of the Class 11 Physics textbook is titled “Units and measurements”.The chapter introduces the SI system of units and explains the different types of units, such as fundamental units and derived units. It also discusses the various methods of measurement, including direct and indirect methods, and introduces the concept of errors in measurement. Here are some key points that you can expect to learn in this chapter:

1. Physical quantities: Physical quantities are properties that can be measured and expressed quantitatively, such as length, mass, time, temperature, electric current, etc.
2. Units of measurement: Units of measurement are standardized values used for measuring physical quantities. There are two types of units – fundamental units (such as meter, kilogram, second, ampere) and derived units (such as velocity, acceleration, force, energy, power, etc.).
3. System of units: A system of units is a set of fundamental and derived units that are used for measuring different physical quantities. The most widely used system of units is the International System of Units (SI), which is based on seven fundamental units.
4. Methods of measurement: There are two methods of measurement – direct and indirect. Direct measurement involves measuring a physical quantity using a measuring instrument, such as a ruler, thermometer, weighing balance, etc. Indirect measurement involves measuring a physical quantity by measuring some other related quantity and using mathematical equations to derive the desired quantity.
5. Errors in measurement: Errors are the difference between the measured value and the true value of a physical quantity. Errors can be classified into two types – systematic errors and random errors. Systematic errors arise due to a flaw in the measuring instrument or the measurement process, while random errors are caused by fluctuations in the measurement conditions.
6. Dimensional analysis: Dimensional analysis is a method used to check the correctness of an equation and to derive new relationships between physical quantities. It involves checking the dimensions (units) of the physical quantities involved in an equation and ensuring that the dimensions on both sides of the equation are the same.
