Context: In physics, gravity (from Latin gravitas 'weight') is a fundamental interaction which causes mutual attraction between all things with mass or energy. Gravity is, by far, the weakest of the four fundamental interactions, approximately 10^38 times weaker than the strong interaction, 10^36 times weaker than the electromagnetic force and 10^29 times weaker than the weak interaction. As a result, it has no significant influence at the level of subatomic particles. However, gravity is the most significant interaction between objects at the macroscopic scale, and it determines the motion of planets, stars, galaxies, and even light.


Question: What is gravity?

Gravity can be described as the fundamental interaction which causes mutual attraction between all objects with mass or energy. While it is considered the weakest of the four fundamental forces (electromagnetic, strong interaction, and weak interaction), it is most significant force at the macroscopic scale and can influence the motion of planets, stars, galaxies, and light.
