Law of Conservation of Energy || Work and Energy || in Hindi for Class 9

In this Science (Physics) video in Hindi for Class 9 we explained and proved the law of conservation of energy. This is a topic from Chapter 11 - 'Work and Energy' for class 9th from NCERT. This law states that the energy of an isolated system (an object or a group of objects) remains constant unless it gains energy from outside or imparts energy to an outside object. In other words, energy can neither be created nor be destroyed. We can prove this law in case of a falling body. As a body falls its potential energy reduces and its kinetic energy increases. And we can easily prove that the sum of the kinetic energy and the potential energy remains the same. ********************************************************* 🔴 Click here to watch the whole playlist on Chapter 11 : 'Work and Energy' for Class 9 :    • Work and Energy (Introduction) || in Hindi...   ******************************************************** Previous videos :- 🔴 Work and Energy (Introduction)    • Work and Energy (Introduction) || in Hindi...   🔴 What is Work    • What is Work ?? (Work and Energy - 2) in H...   🔴 Sine, Cosine and Tangent (Trigonometry)    • A little talk on Sine, Cosine and Tangent ...   🔴 Advanced concept on Work (Dot Product)    • Advanced concept on Work (Dot Product) || ...   🔴 Kinetic Energy    • Kinetic Energy || Work and Energy || in Hi...   🔴 Kinetic Energy - Part 2 (Numericals)    • Kinetic Energy - Part 2 (Numericals) || Wo...   🔴 Kinetic Energy is Relative to the Observer    • Kinetic Energy is Relative to the Observer...   🔴 Force required to LIFT an object against Gravity    • Force required to LIFT an object against G...   🔴 Potential Energy    • Potential Energy || Work and Energy || in ...   ********************************************************
