Conservation of Energy in S.H.M | Chapter 14 Simple Harmonic Motion | 12th Class New Physics |

Conservation of Energy in S.H.M. | Topic 14.7 | Chapter 14 Simple Harmonic Motion | 12th Class Physics New Book 📚📖 This video is part of 12th Class Physics (Intermediate Part II Physics), Chapter 14 – Simple Harmonic Motion, Topic 14.7 – Conservation of Energy in S.H.M. It is specially prepared for FSc Part II and ICS Part II students. In this lecture, you will learn the complete concept of Conservation of Energy in Simple Harmonic Motion through board-style theory, mathematical derivations, and detailed conceptual explanations exactly as required for board examinations. The lecture begins with the concept of Conservation of Energy in Simple Harmonic Motion and explains how Potential Energy and Kinetic Energy continuously transform into each other during oscillation while the Total Mechanical Energy remains constant in the absence of frictional forces. Using a clear mass-spring system diagram, the expressions for Potential Energy (P.E.) and Kinetic Energy (K.E.) are derived step by step. The energies at the mean position and extreme positions are calculated in detail to prove mathematically that the total energy remains constant throughout the motion. The lecture also explains the energy transformation process with clear reasoning and graphical interpretation, making this important board topic easy to understand. This lecture covers: • Introduction to Conservation of Energy in S.H.M. • Energy Transformation in Simple Harmonic Motion • Potential Energy of a Mass-Spring System • Derivation of Potential Energy Formula • Kinetic Energy of a Mass-Spring System • Derivation of Kinetic Energy Formula • Total Mechanical Energy in S.H.M. • Energy at the Mean Position • Energy at the Extreme Positions • Proof of Conservation of Energy in S.H.M. • Energy Conversion Between K.E. and P.E. • Graph of Kinetic Energy, Potential Energy, and Total Energy versus Displacement • Complete Board-Style Theory and Step-by-Step Mathematical Derivations Exercise Long Question Covered: Derive expressions for K.E. and P.E. of the mass-spring system executing S.H.M. Also prove that its total energy remains same. This is one of the most important long questions of Chapter 14 – Simple Harmonic Motion and is highly important for board examinations. Every concept is explained on the whiteboard with complete theory, detailed derivations, diagrams, and conceptual discussion so that students can confidently solve long questions as well as strengthen their understanding of the topic.
