Centre of Gravity | Middle School Science | Khan Academy

Why do objects balance or fall? The secret lies in the centre of gravity — the point where all of an object's weight appears to act. In this video, we explore what the centre of gravity really means, how to find it using simple experiments, and how it affects everything from toy designs to human movement. From balancing forks to tightrope walkers, discover how this invisible point controls real-world physics. Whether you're sitting, standing, or building bridges, the centre of gravity is always at work. Watch, learn, and explore the science behind balance in everyday life!
