The document discusses the center of gravity, which is the point where a body's weight is concentrated and can be balanced without rotating. For regularly shaped bodies, the center of gravity is located at the geometric center. The center of gravity in the human body is affected by age, sex, and body build, and is generally located around the second sacral vertebra, 6 inches above the crotch and at 55% of a person's height. However, the location shifts with changes in position and load carrying.

2. •The point where a body may be hung
without rotating.

3. Location of Center of Gravity in
Regularly-Shaped Bodies

4. There are objects whose center of gravity lie
outside the body.

5. How about in the human body?

6. 1.Age – relatively higher in infants and
children compared to adults
2.Sex – higher in males than in females
3.Body build – located in the vicinity of
the more massive part of the body

General Descriptions of the Location of
Center of Gravity

10. Location of center of gravity shifts whenever
the person shifts position.

the body.
