How is gravity related to physics and astronomy?

Answer 1

How does Astronomy involve Chemistry?There is actually quite a lot of Chemistry used in various areas of Astronomy.

One big application is in the identification of spectral lines. Each element and molecule emits light at very specific frequencies, so we can use this fact to try to identify the composition of Astronomical objects from the light they emit. This can be hard, as there will be lots of things mixed in together all emitting different spectral lines (a famous astronomer once likened it to trying to reconstruct a piano from the noise it makes as it falls down the stairs!).

Areas where chemistry is particularly important is in studies of our Solar System, where the bodies can have very interesting composition. Another area is looking at Molecular Clouds (clouds with molecules in them) from which it is believed that stars form.

Answer 2

The story of gravity is about an apple! Strange isn't it? Sir Isaac Newton was sitting underneath a tree and an apple fell just beside him! Luckily not on his head! He finally thought up the idea of gravity and has been famous since! Unfortunately he is DEAD!!!!!

Answer 3

astronomy mostly uses the principles and laws of physics. Like gravitation force responsable for the motion of planets, radiations, optics(physics) is used in astronomy, and instruments used by astronomers like telescope are also operated by physics

Answer 4

If you meant to ask "What is the relationship betwee physics and Astrology?", then the answer is "Nothing whatsoever". Astrology is akin to magic or mysticism, and has nothing at all to do with the real universe.

Answer 5

Astronomy is a branch of physics that studies the physical universe outside the Earth.

Answer 6

Astronomy was Physics in the beginning (let there be Light!). Now Astronomy is a subset of Physics.

Answer 7

9.8 m/s.

It is the mutual attraction between two masses

Answer 8

Because physics is about matter and energy, gravity is included into that as it is energy.

Answer 9

Physicists study about forces and such and they are forces of the universe as collisions of asteroids, etc.

Answer 10

A branch of chemistry is cosmochemistry: study of compounds in cosmos, study of the compositions of stars, planets, meteorites, comets etc.
