👉 Tmesis is a concept in physics that describes the relationship between two bodies with respect to their mutual gravitational attraction. It can be defined as the force of attraction between two masses or bodies exerted by each other on each other, which is proportional to the product of their masses and inversely proportional to the square of the distance between them. This principle explains why objects in orbit are attracted toward each other, and it also explains why a planet attracts its moons with mutual gravitational attraction.
