Quite simply, physics is used to explain how and why things happen in the physical universe. For example, Newton's first law of physics, an object in motion tends to stay in motion, helps explain the orbit of about . The planets are in constant motion at a particular speed around the sun. The planets try to move in a straight ahead motion but their route is altered by the existence of gravity. This is called Astro-physics.

In his general and special laws of relativity, Einstein was giving definition the laws of physics previous unknown. These laws of physics helped us understand the speed of light which in turn helps us measure distances in the universe, light years.

We use physics to explain the four forces of nature: the strong force (nuclear), weak force (radiation), gravity and electro-magnetism. Anytime we look at a star all four of those forces come into play in describing the star we are looking at.

And so without physics, astronomy lacks definition.

Why is a parsec useful in astronomy?

It's the largest unit of distance. To measure distance of astronomical objects, astronomers usually measure the parallax angle. The parsec can be used readily with that data. So it...

In what order do these astronomy terms go from smallest to biggest: Earth, Universe, Milky Way galaxy, Jupiter, Asteroid, and the Sun?

Asteroid, Earth, Jupiter, Sun, Milky Way (galaxy), universe. They will often miss out one or more terms and may add in others e.g. comet instead of asteroid. You also need...

In astronomy, what is a weak force?

It is meditated by W and Z bosons. It only is effective if at shorter distances, but is powerful than the gravity itself. It is responsible for natural radiation present...

How does the definition of strong nuclear force differ between astronomy and physics?

Astronomy is, essentially, applied physics (with the relatively recent developments of astro-chemistry and astro-biology, this isn't as clear cut as it used to be, but overall I think it still...

How are the four fundamental forces applied in the study of astronomy?

The residual strong nuclear force is responsible for binding protons and neutrons into atomic nuclei. The weak nuclear force is responsible for radioactive beta decay and in particular converting protons...

How do you distinguish between astronomy, cosmology, and astrophysics? What are their links with physics?

Astronomy is about the observation of bodies in the sky. These include planets, moons, comets, stars, galaxies, nebulae and other objects. It involves determining the position, distance, motions and brightness...

Why are general and special relativity important to the field of astronomy?

Unlike most people think, general relativity has nothing in General in a sense, neither do the special relativity that has something 'special'. Like Newton's laws, General relativity makes its starting...

If the law of physics that determines maximum density of matter is broken during the initial creation of a black hole, then shouldn't all laws of physics be invalidated within the event horizon (Schwarzschild radius) of a black hole?

were first predicted by the Schwarzschild solution to the General Theory of Relativity. As not even light can escape the event horizon of a black hole, then we can...
