Introduction to Energy

Categories Energy, Physics

Course Description

Introduction to Energy is a foundational physics module that unveils the invisible force powering everything—from the flicker of a lightbulb to the fusion of stars. Energy is the capacity to do work, and it manifests in countless forms across nature and technology.

This lesson explores the core types of energy, how it moves and changes form, and why the laws of conservation are central to science and engineering. Whether you’re a student, educator, or curious mind, this course connects the abstract concept of energy to the tangible world around you.

What You’ll Learn

⚡ By the end of this lesson, you’ll be able to:

  • Identify the fundamental forms of energy, including:
    • Kinetic Energy – energy of motion
    • Potential Energy – stored energy due to position or condition
    • Thermal Energy – energy from heat
    • Chemical Energy – stored in molecular bonds
    • Electrical Energy – from moving electrons
    • Nuclear Energy – from atomic nuclei
    • Radiant Energy – carried by electromagnetic waves (e.g., light)
  • Understand energy transformations and transfers, such as:
    • A toaster converting electrical energy into thermal energy
    • A roller coaster transforming potential energy into kinetic energy
    • Photosynthesis converting radiant energy into chemical energy
  • Explore the Law of Conservation of Energy:
    • Energy cannot be created or destroyed—only transformed from one form to another
    • Learn how this principle applies to closed systems and real-world processes
    • Analyze energy efficiency and losses (e.g., heat dissipation)
