[Q3] ENERGY TRANSFER

Image
  Exploring the Transformation of Energy: Sound, Heat, Light, and Electricity By: Pj Miana   Introduction: Energy is all around us, and it can take many forms. In this lesson, we'll delve into how different types of energy—sound, heat, light, and electricity—can be transformed from one form to another. Understanding these transformations helps us comprehend the world and the technology we use every day.   1. Sound Energy: Sound energy is produced by vibrations traveling through a medium, such as air, water, or solids. It can be transformed in various ways:   - Mechanical to Sound : When an object vibrates, it creates sound waves. For example, when you pluck a guitar string, the mechanical energy of your hand's motion is transformed into sound energy.   - Sound to Electrical : Microphones transform sound waves into electrical signals. These signals can then be amplified and converted back into sound through speakers.   2. Heat Ener...
