Work, energy and power might sound like things only scientists worry about, but they’re actually part of your everyday life. Every time you lift your school bag, ride your bike, or even plug in your phone to charge – you’re dealing with work, energy or power. Understanding how they work together helps us understand how the world moves, changes and gets things done.

In this topic, you’ll explore how energy can’t be created or destroyed, why work isn’t always about homework, and how power shows how quickly energy is used. We’ll explain key ideas in simple steps, with examples you’ve probably seen around your house or garden. You’ll discover how everything from a football kick to a moving train uses energy and does work. And by the end, you’ll be able to explain how your own body is a power machine too!
