What are the forces acting on stars?
The forces acting on stars are gravitational and electromagnetic. Stars have charge and electromagnetic fields and charge generate forces, F=qE + qvxB. The so-called "dark (missing) matter in galaxies" is a manifestation of the electromagnetic forces on stars. Roughly a star with mass m in the galaxy, is acted on by the galactic magnetic field B. This is similar to the mass spectrometer. mv^2/r = qvB = qvuI/r = qvzI/cr Thus v=qzI/mc the velocity of v is independent of the radius and depeds on the charge to mass ration, q/m.
What is the birthplace of stars called?
The birthplace of stars is called a stellar nursery or star-forming region. These regions are often found within interstellar clouds of gas and dust where gravitational forces cause these materials to collapse and form new stars.
How are nebulae and stars related?
Nebulae are large clouds of dust and gas in space where stars are born. Within a nebula, gravitational forces can cause the gas and dust to collapse and form a protostar, which eventually ignites nuclear fusion and becomes a star. Therefore, nebulae are the birthplaces of stars, and stars are formed from the material within nebulae.
How does gravity cause fusion in stars?
Gravity plays a crucial role in the fusion process within stars by compressing their core. As a star forms, gravitational forces pull matter inward, increasing the pressure and temperature in the core. When the temperature reaches millions of degrees, hydrogen nuclei can overcome their repulsion due to electrostatic forces and collide with enough energy to fuse into helium, releasing vast amounts of energy in the process. This energy counteracts gravitational collapse, creating a stable balance that allows the star to shine for billions of years.
What is the opposite of dark matter and how does it interact with the universe?
The opposite of dark matter is regular matter, which includes everything we can see and touch. Regular matter interacts with the universe through electromagnetic forces, such as light and heat, and makes up stars, planets, and living organisms.
Does a accretion spin?
Accretion is the process by which matter is accumulated by gravitational forces. While the accumulation of matter can lead to the formation of objects that spin, such as stars and planets, accretion itself does not inherently involve spinning.
Is the sun a natural force?
The sun is a natural physical object, part of a group of objects called stars. These are created by the accumulation of matter through a natural force called gravity.Such objects can then produce certain natural forces such as electromagnetic radiation. Light, heat, etc.
What is the ending of dead stars?
When stars die, the matter(dust and dirt) is spread out where the star once lived. The matter would continue to drift outward, but gravitational forces pull the matter back together overtime. Eventually, the recollected star matter forms into a dense ball again and creates energy. Thus, the death of stars leads to new stars - it is a circle of life.
How do stars form?
Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars.
Which type of forces are present in stars that they are stationary still they are not falling?
Gravity and inertia are the two forces that act on all matter in the universe. If there were only two stars in the universe and they were standing still, the force of gravity would cause them to eventually fall together and collide. But there are hundreds of billions of stars in the Milky Way alone, and billions of other galaxies out there, and NOTHING is standing still; everything is in motion. The primary forces that keep the stars from falling together is the rotation of the Milky Way; all the stars appear to orbit the center of the Milky Way.
What is the explanation for each branch of science?
Chemistry-study of properties and composition of matter Physics-deals with forces,motion and energy and their effects on matter Biology-study of living organisms Earth Science-study of planets and its place in the universe Geology-study of earth,its matter and the processes that form and cjange it Astronomy-study of objects in space including stars,planets and comets Meteorology-study of weather and the forces and processes that cause it Oceanography-study of Earth's oceans
Where do new stars get their matter from?
new stars can get matter from old stars and comets really anything it can get its hands on
What force exerted the matter after the big bang?
After the Big Bang, it was the force of gravity that exerted the most influence on matter. Gravity acted to pull matter together, leading to the formation of galaxies, stars, and other cosmic structures. Other forces such as electromagnetism and the strong and weak nuclear forces also played important roles in shaping the universe.
Do stars matter?
The vast bulk of your mass was at one time part of a star, so if you matter, then stars matter.
What objects do forces act on?
Forces act on all objects with mass. This includes everyday objects like books, cars, and furniture, as well as celestial objects like planets and stars. Forces can cause objects to move, accelerate, deform, or rotate.
What force do scientist think was responsible for clumping matter togerher to form the first stars after the big bang?
Gravity. Please note that the other forces aren't usually relevant at the usual distances between stars, or between galaxies.
Is stars matter?
yes
