Gravity is a force between two objects with mass why doesn’t a person feel a gravitational force between him and another person
While gravity is indeed a force between two objects with mass, such as a person and another person, we don't usually feel this force explicitly between ourselves and others. This lack of perception is mainly due to the gravitational force between two individual humans being relatively weak compared to other forces acting on us.
The force of gravity is proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them. Since humans have relatively small masses compared to some other celestial bodies (such as the Earth), the force of gravity between individuals is quite small. Additionally, the distance between two people is typically very small compared to other distances in the universe, leading to an even weaker gravitational force between them.
Furthermore, as humans, we are constantly experiencing the gravitational force of larger objects like the Earth, which is far greater than the force between two individuals. This dominant force from Earth's gravity essentially masks the relatively weak force between people. Therefore, we don't usually perceive the gravitational force between ourselves and others, as it is overshadowed by other forces we experience regularly.
