Gravity is an attracting force that exists because of the mass of the Earth. The word gravity comes from the Latin "gravitas", which means weight. The force of gravity is one of the four fundamental forces of nature. read more
Everything has a gravitational field. You, your phone you typed your Quora question on, EVERYTJING has a gravitational pull. read more
For example, in our own Solar System, not only does the Sun exert gravity on all the planets, keeping them in their orbits, but each planet exerts a force of gravity on the Sun, as well as all the other planets, too, all to varying degrees based on the mass and distance between the bodies. read more
Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. read more
The force of Earth’s gravity is the result of the planets mass and density – 5.97237 × 10 24 kg (1.31668×10 25 lbs) and 5.514 g/cm 3, respectively. This results in Earth having a gravitational strength of 9.8 m/s² close to the surface (also known as 1 g), which naturally decreases the farther away one is from the surface. read more
