Class 11 Physics New Book 2025 | Work, Energy & Power | Numerical Problems 4.1 & 4.2 Solved

Welcome to Science Teaching Zone!
In this video, I present a detailed step-by-step solution of Numerical Problems 4.1 and 4.2 from Class 11th Physics New Book 2025, Chapter 4: Work, Energy, and Power. This chapter is fundamental to understanding the concepts of work done, kinetic and potential energy, and power, which are key topics in your Physics syllabus.

The problems covered in this video will help you grasp the practical application of formulas related to:

Work done by a force

Kinetic energy and its calculation

Potential energy and its relation to height

Power and its calculation in different scenarios


I explain each problem carefully to help students understand the method of solving numerical problems, including unit conversions and formula derivations. Whether you are preparing for your exams or want to strengthen your Physics fundamentals, this video is perfect for you.

This lecture is aligned with the Punjab Curriculum & Textbook Board (PCTB) syllabus for the year 2025. Make sure to watch carefully, take notes, and practice along with the video to master these important problems.
