11th class physics chapter 1 | Class 11 physics chapter 1 | 11th physics chapter 1 Physical quantities and their units (1.1) from Class 11 Physics Chapter 1 Measurements starts with one of the most important topics of the entire syllabus: Physical Quantities and Their Units. If you are studying 11th class physics new book 2025 (Punjab Board / PCTB), this lecture will help you build a strong conceptual foundation right from day one. In this video, we explain Chapter No. 1 – Measurements, Topic 1.1: Physical Quantities and Their Units, using simple language, real-life examples, and exam-oriented explanations. This lecture is specially designed for FSc Part 1, ICS, FA (IT), and Pre-Medical students who want clarity before moving to numericals and exercises. A physical quantity is any property of nature that can be measured, such as length, mass, time, temperature, electric current, and luminous intensity. To measure these quantities accurately, we need standard units, and that’s where SI Units (International System of Units) come in. In this lecture, we clearly discuss base quantities, derived quantities, base units, and derived units according to the new syllabus 2025. You will learn: What are physical quantities in physics Difference between base quantities and derived quantities Why units are necessary in measurements Introduction to SI units system Examples of commonly used derived units Common mistakes students make in exams How this topic helps in numericals, board exams, MDCAT & ECAT This lecture is perfect for students searching for: 11th class physics chapter 1 measurements physical quantities and units class 11 physics class 11 physics new book 2025 lecture 1st year physics measurements explanation physics class 11 Punjab Board new syllabus Whether you are starting the new academic year or revising concepts before exams, this video will make Measurements Chapter 1 easy and stress-free.
