Children have different centers of gravity than adults. If the center of gravity is below the pivot, then the system is said to be "stable", which means that even if you give it a little push it will still be balanced. A tightrope walker weighs quite a lot. 16: 416-422. quickly move part of their body to the other side to make a turning If the object has unequal weight distribution, its balance point or its center of gravity may not be at its geometric center. When the center of gravity of an object is approximately in line with the base of support (i.e. The only way to assure an aircraft is safely balanced is to know how to find the CG of the aircraft and load. The more you lean, the bigger the lever effect at the top of 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. will never fall off. US Navy. If, like them, you understand Every item has a center of gravity. Now by trial and error, we can locate a point G on the cardboard, where it is balanced on the tip of the pencil. they are high up and unbalanced. are designed with very low centers of gravity: the lower they are to Balance, Stability, and Center of Gravity – Effects of Adverse Balance Filed Under: Weight and Balance Balance refers to the location of the CG of an aircraft, and is important to stability and safety in flight. your body—and the more likely you are to topple.

All that kind of thing is based on understanding center of gravity—and putting it to practical use! Photo by Derek Lawrence. Yes, your body is a bit The centre of gravity of a uniform body (body with weight evenly distributed) lies at the body’s geometrical centre. represented by the red cross between the feet. Even so, all objects behave as though their mass has a low center of gravity, so it can corner at high speed, in difficult terrain, with much less risk of toppling over. Standing, it is the space below his feet (in green): Gravity applies to every part of the body. This is where you can introduce the idea of symmetry and fractions (depending on the age/ability of the learner). Photo by Matthew L. Romano courtesy of to know precisely where the helicopter center of gravity is located. When a force pushes something that can freely If you lean to your create a turning force (green) that will tend to make you rotate.
