Energy, Work and Machines

Categories Physics

Uncover the forces that drive our world.

This course is a hands-on journey into the heart of physical science, where energy isn’t just a concept—it’s the invisible thread connecting everything from boiling water to lifting skyscrapers. Students will explore how energy is created, transferred, and transformed, and how it powers the machines and systems we rely on every day.

🔍 What You’ll Learn:

  • Introduction to Energy
    Understand the different forms of energy—kinetic, potential, thermal, chemical—and how they interact in natural and engineered systems.
  • Heat and Energy Transfer
    Dive into the mechanisms of heat flow: conduction, convection, and radiation. Learn how insulation works, why metal feels cold, and how energy efficiency shapes modern design.
  • Work, Power, and Simple Machines
    Explore the physics of motion and force. Discover how levers, pulleys, inclined planes, and other simple machines make work easier—and how power is measured and optimized in mechanical systems.

 

🌟 Why It Matters:

From the gears in your bicycle to the turbines in a power plant, energy and machines shape the way we live. This course connects theory to practice, helping learners see the physics behind everyday experiences—and empowering them to think critically about how we use energy in a changing world.
