Tidal Forces

Tidal forces are the gravitational forces that cause the deformation of an astronomical body, such as a planet or a moon, due to the differential gravitational pull of another astronomical body. These forces are responsible for the tides on Earth and can also cause significant changes in the shape and rotation of moons and planets. Tidal forces are particularly important in the study of celestial mechanics and the dynamics of planetary systems, as they can affect the orbits and stability of planets and moons. In addition, tidal forces can generate internal heating and geological activity, such as volcanic eruptions and tectonic activity, on moons and planets.
