Gravity
Gravity is the universal force of attraction acting between all matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter.
However, gravity is the most significant interaction between objects at the macroscopic scale, and it determines the motion of planets, stars, and galaxies. At Earth’s surface, the acceleration of gravity is about 9.8 meters per second.
