Gravity is a force between any two objects with mass why doesn't a person feel a gravitational force between him and herself and another person
According to Newton's law of universal gravitation, the gravitational force between two objects depends on the mass of both objects and the distance between them. The force is directly proportional to the product of their masses and inversely proportional to the square of their distance.
In the case of a person and another person, both individuals have mass. So, theoretically, there is a gravitational force between them. However, the force is extremely weak compared to other forces acting on us, such as the force exerted by the Earth's gravity.
The gravitational force between two ordinary-sized people is so small that it is practically negligible. The mass of an average person is around 70 kilograms, and the distance between the two people is very small when compared to the distance between us and the Earth.
As a result, the gravitational force between two people is too insignificant to be noticed or experienced. The forces exerted by our everyday interactions, like standing on the ground or moving, are much stronger than the gravitational force between people.
