PHYSICS - Energy - Conservation of Energy

The video tutorial explores the concept of energy, its storage, and transfer methods. It explains how energy is stored chemically, such as in petrol, and how it requires oxygen to release energy. The tutorial covers various energy transfer methods, including mechanical, electrical, heating, and radiation. Practical examples, like cooking with a gas stove and using a battery-powered drill, illustrate these concepts. The video emphasizes energy conservation, using Sankey diagrams to show energy flow and waste. It concludes with a reminder to conserve energy sources to prevent depletion.
