To see how that works, try opening a door by pushing the handle with oneįinger. Taller you are, the more you'll turn because your whole body isĪcting like a lever, helping the force of gravity to turn you Pulls things downward, but here it's making you turn in a circle! The
You might think gravity is something that Not actually moving but turning about your ankles. Where your whole body feels like it's about to topple over. Thinking about center of gravity helps us answer questions like this. So they create more down-force on the left to compensate. The pilot has to adjust the pitch of the rotors 2) A helicopter carrying a side load has its center of gravity shifted to the left, as we look at the picture. 1) This giant C-5 Aircraft is having its center of gravity calculated in a special weight and balance hangar at Edwards Air Force Base in California. Photo: Why does center of gravity matter? If you want to fly an aircraft safely, having a balanced load is important. There's more weight in the top half of your body than in the bottom Object, like your body, the center of gravity is slightly higher than your waist because A simple object like a ball has its center of gravity inĪ very obvious place: right at its center. (the stuff they're made from) is concentrated at a point called their center of Even so, all objects behave as though their mass NotĮverything moves like this when gravity acts on it. Throw a ball in the air and gravity pulls it straight back down. How does it help to know about center of gravity?.Why does gravity make your body tip over?.Photo of Eoreum (also called Jultagi), Korean tightrope dancing, courtesy of United States Army Garrison Public Affairs. She's carrying is just a funny little touch, but it's more important than it looks: it gives the walker an easy way to redistribute her weight and quickly correct any wobbles that could send her to the ground.
Photo: A tightrope walker has an instinctive command of physics. If, like them, you understandĪ simple concept called center of gravity, you'll find Instinctively understanding the physics of forces Tiptoeing over the high wire, they often teeterĪnd wobble from side to side just to entertain us, yet they hardlyĮver fall off. Tightrope walkers understand thisīetter than anyone. Sometimes gravity can make things turn and topple over, especially if We think of gravity as a force that pulls things downward (towardĮarth's center), but it doesn't always work like that. What goes up must come down-that's one way of understanding gravity.
