The human center of gravity is the point where the human body rests under normal conditions without rotating, remaining balanced without active effort to remain upright. An unstable center of gravity requires only a small push to ruin someone's equilibrium, whereas a stable equilibrium is much stronger and can remain stable even under significant force.Know More
The natural center of gravity shifts according to posture, with a lower center of gravity, or CG, creating a stronger balance. Crouching, sitting and kneeling all create a stable CG, making it easy to remain balanced even when pushed by outside factors. Standing upright is less stable, as the CG is higher and easier to unbalance.
Center of gravity is only one part in maintaining balance, with several other factors determining if someone can remain upright. An individual will maintain balance with an increase of friction in their footing or being assisted by special footwear. Someone balancing on a rope or a wooden beam will crouch down to lower their center of gravity, actively equalizing their balance in the process. Individuals with greater mass have a stronger balance due to a more stable center of gravity, requiring less effort to remain upright than shorter or smaller people.Learn more about Particle Physics
The human heart is a pump made of muscle that pushes blood through the human body. The heart contains the aorta, anterior vena cava, semilunar valve, right atrium, right ventride, posterior vena cava, pulmonary artery, pulmonary vein, septum and left ventricle.Full Answer >
The majority of the human heart is located to the left of the center of the chest and behind the sternum. The remaining third of the human heart is on the right side of the mid-line of the chest.Full Answer >
The warmest parts of the human body are the head, chest and armpits, according to the Journal Gazette of Fort Wayne, Ind. Conversely, the coldest parts are the feet and toes, which are farthest from the warm-blood-pumping heart.Full Answer >
It takes 24 to 72 hours for beef to digest within the human body. The length of time it takes for beef or any food to pass through the digestive system is dependent on the individual's metabolism and the rate at which the muscles contract to move the contents through the system.Full Answer >
