Class 9 Chapter 10 | Work & Energy | Part 2 | Energy (KE+PE), power & law of conservation of energy

Master Energy, Power, and Conservation Laws! (Class 9 Science) Everything You Need to Know About Kinetic & Potential Energy Welcome back! In today’s video, we dive deep into the world of Work and Energy. We’ll break down the scientific definitions, explore the different forms of energy, and learn how to calculate them using real-world examples. What you will learn in this video: What is Energy? Understand that energy is the capacity to do work. We’ll look at how it transfers from one object to another. Kinetic Energy (E_k): The energy of motion! We explain why a speeding bullet or a falling coconut possesses energy and how to use the formula E_k = \frac{1}{2}mv^2. Potential Energy (E_p): Energy stored due to an object's position or configuration. Learn about gravitational potential energy (E_p = mgh) and how energy is stored in stretched rubber bands or wound-up toys. The Law of Conservation of Energy: A fundamental law of nature! Discover why energy can neither be created nor destroyed, only transformed from one form to another, keeping the total energy constant. Power (P): It’s not just about doing work, but how fast you do it. We define power as the rate of doing work (P = \frac{W}{t}) and explain units like Watts (W) and Kilowatts (kW).
