Major Physics
ASTROPHYSICS
Astrophysics is a branch of space science that applies the laws of physics and chemistry to explain the birth, life and death of stars, planets, galaxies, nebulae and other objects in the universe.
Sun
-
-
-
mass consists of hydrogen and helium with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron.
Stars
-
Many other stars are visible to the naked eye from Earth during the night, because of very far from the Earth.
Galaxy
Galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter.
Galaxies are categorized according to their visual morphology as elliptical,spiral, or irregular.
-
The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun.
Exoplanet
-
As of 1 October 2019, there are 4,118 confirmed exoplanets in 3,063 systems, with 669 systems having more than one planet.
-
Nebulae
is an interstellar cloud of dust, hydrogen, helium and other ionized gases
Used to describe any diffuse astronomical object, including galaxies beyond the Milky Way
-
A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by.
Cosmology
-
It is the scientific study of the origin, evolution, and eventual fate of the universe
Astronomy
-
It uses mathematics, physics, and chemistry in order to explain their origin and evolution.
Objects of interest include planets, moons, stars, nebulae, galaxies, and comets.
Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation.
Mechanics
Study of the behavior of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment.
Quantum Mechanics
fundamental theory in physics which describes nature at the smallest scales of atoms and subatomic particles.
Restricted to discrete values , objects have characteristics of both particles and waves
gradually arose from theories to explain observations which could not be reconciled with classical physics
provides information about the probability amplitude of position, momentum, and other physical properties of a particle.
Classical Mechanics
describes the motion of an objects, from projectiles to parts of machinery, and astronomical objects.
-
Kinematics
a branch of classical mechanics that describes the motion of objects and systems of bodies without considering the forces that cause them to move.
