Question

Explain gravity in about 10 lines

Answer 1

Gravity, or gravitation, is a natural phenomenon by which all things with massare brought toward (or gravitate toward) one another, including objects ranging from atomsand photons, to planets and stars. Since energy and mass are equivalent, all forms of energy (including light) cause gravitation and are under the influence of it. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides. The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing, forming stars – and for the stars to group together into galaxies – so gravity is responsible for many of the large scale structures in the Universe. Gravity has an infinite range, although its effects become increasingly weaker on farther objects.

Answer 2

1)Gravity is really an unknown force. 2)We can define it as a field of influence, and that it effects the entire existence of the universe. 3)Some people think that gravity consists of particles called gravitons, which travel at the speed of light. 4)The only thing we do know is how gravity operates in different parts of our universe.
5)Without gravity, there would be no space and time.

6)There is a legend that says that Galileo once dropped two objects off the Leaning
Tower of Pisa to show that the heavier of the two objects

dropped faster. 7)If a feather and hammer were the two objects he used then obviously the hammer would hit the ground first. 8)This is due to air resistance, which is the force air exerts on a moving object.
