Imaginary point in a body of matter
- Center of gravity, in physics, an imaginary point in a body of matter where, for convenience in certain calculations, the total weight of the body may be thought to be concentrated. In a uniform gravitational field, the center of gravity is identical to the center of mass.

Human center of gravity is a term that has implications for all things related to posture, including issues such as swayback, the design of posture exercise programs, and much more. Gravity is a downward pull or force that the earth exerts on your body. Your centre of gravity is the point where the mass of the body is concentrated. Similar to Cente...
In the anatomical position, the COG lies approximately anterior to the second sacral vertebra , at the center of the pelvis. However, since human beings do not remain fixed in the anatomical position, the precise location of the COG is always shifting with each movement of the body and limbs. The proportion of body weight of the limbs, trunk, and h...
The position of COG varies by individual, especially differing athletes. An athlete with longer and/or larger legs will likely have a lower COG, unless their upper body is also a relatively large structure and balances the mass of the lower body. It is seen that in runners, the COG is in the lower region (inferior) of the pelvis, and in front of (a...
The direction of the force of gravity through the body is downward, towards the centre of the earth and through the COG. This line of gravity is important to understand and visualise when determining a person's ability to successfully maintain balance. When the line of gravity falls outside the Base of Support(BOS), then a postural reaction is need...
Examples of altered COG: 1. Obese individuals have been shown to have a greater risk of falling (related to dynamic, rather than static components). This could be explained by the fact that an obese individual should not encounter a balance difficulty if their centre of gravity remains within their base of support. This is the case in a static situ...
The Centre of gravity is a theoretical point in the body where the body’s total weight is thought to be concentrated. It is important to know the centre of gravity because it predicts the behaviour of a moving body when acted on by gravity.
- Archimedes of Syracuse discovered the centre of gravity.

Nov 24, 2022 · A simple object like a ball has its center of gravity in a very obvious place: right at its center. But in a more complex object, like your body, the center of gravity is slightly higher than your waist because there's more weight in the top half of your body than in the bottom half.
Apr 4, 2023 · Gravity is a downward pull or force that the earth exerts on your body thereby giving you weight. Your center of gravity (COG) is the point about which a body’s weight is equally balanced in all directions.
The center of gravity of a body is a point where the weight of the body acts and the total gravitational torque on the body is zero.
Mar 12, 2024 · The center of gravity of an object (blue dot) is the average location of all gravitational forces. This average location does not necessarily have to be on the object. Image Credit: D. Gordon E. Robertson via wikimedia commons [1] Freely rotating objects tend to rotate around their center of mass.
