Why don’t we feel gravitational attraction between two people?

• The gravitational force is too weak

• The distance is too large

• Mass of people is negligible

• Earth's gravity overpowers it

What is the gravitational force?

• The gravitational force is the force of attraction between two objects with temperature.

• The gravitational force is the force of attraction between two objects with mass.

• The gravitational force is the force of repulsion between two objects with mass.

• The gravitational force is the force of attraction between two objects with charge.
