Külgetõmbega

Külgetõmbega, meaning "with gravity" or "gravitationally" in Estonian, refers to the influence of gravitational forces. In physics, it describes the mutual attraction between any two objects that possess mass. This force is fundamental to the structure and behavior of the universe, governing the motion of planets around stars, stars within galaxies, and galaxies within clusters. The strength of this attraction depends directly on the masses of the objects involved and inversely on the square of the distance separating them, a principle famously described by Isaac Newton's law of universal gravitation.

The concept of külgetõmbega extends beyond celestial mechanics. On Earth, it is what keeps us grounded and prevents objects from floating away. It dictates the trajectory of projectiles and influences phenomena like tides, which are caused by the gravitational pull of the Moon and the Sun. Understanding külgetõmbega is crucial for space exploration, enabling scientists to calculate orbits and predict the movements of spacecraft. While Einstein's theory of general relativity provides a more comprehensive description of gravity as a curvature of spacetime, Newton's law remains a highly accurate approximation for most everyday and astronomical applications, forming the bedrock of our understanding of this pervasive force.
