Question

2. What does a body experience at its centre of gravity?
3. Name the factors on which the position of the centre of gravity of a body depends.​

Answer 1

Explanation:

The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated. Because it is a hypothetical point, the COG need not lie within the physical bounds of an object or person.

The position of the centre of gravity of a body of given mass depends on its shape i.e., on the distribution of mass in it. For example, the centre of gravity of a uniform wire is at its mid-point. But if this wire is bent into the form of a circle, its centre of gravity will then be at the centre of the circle.
