Topic 4.8: Interconversion of Potential and Kinetic Energy | Punjab Board PECTAA Book

Welcome to our 1st Year Physics Lecture Series based on the new Punjab Curriculum (PECTAA 2025).
In this lecture, we’ll deeply understand how energy changes from one form to another — a concept that lies at the heart of physics.

🎯 What You Will Learn:

What is Potential Energy and Kinetic Energy?

How energy transforms between potential and kinetic forms

Real-life examples (swinging pendulum, falling ball, roller coaster)

Conservation of Mechanical Energy explained

Mathematical proof of energy interconversion

Relationship between height, velocity, and energy

This topic explains how no energy is ever lost — it only changes form, a key idea for understanding motion, mechanics, and energy conservation laws.

📚 This lecture is part of Chapter 4: Work, Energy and Power from the new 1st year physics book by PECTAA (Punjab Textbook Board).
The explanation is in simple, exam-oriented language with real-life visuals to make learning easy and effective.

🎓 Perfect for: Board exams, test preparation, concept clarity, and strengthening the base for advanced topics in physics.
