How is there gravity
Web6 jan. 2024 · What is gravity? Gravity is a pulling force (always a force of attraction) between every object in the universe (every bit of matter, everything that has some mass) and every other object. It's a bit like an invisible magnetic pull, but there's no magnetism involved. Some people like to call this force gravitation and reserve the word gravity for … WebInside the ISS, there's a downward gravitational pull of about 0.89g, but the station itself is simultaneously accelerating downward at 0.89g -- because of the gravitational pull. …

Because you and your … Web1 jan. 2016 · Basically, gravity is dependent on mass, where all things – from stars, planets, and galaxies to light and sub-atomic particles – are attracted to one another. Depending on the size, mass and...
Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as the curvature of spacetime, caused by the uneven distribution of mass, and causing masses to move along geodesic lines. Meer weergeven In physics, gravity (from Latin gravitas 'weight' ) is a fundamental interaction which causes mutual attraction between all things with mass or energy .
