What forces act on nebula?
The main forces acting on a nebula are gravity, which causes the nebula to collapse and form stars, and radiation pressure, which can push material away from the forming stars. Additionally, magnetic fields can play a role in shaping the structure and dynamics of a nebula.
How does gravity affect the stars moon an planets?
Gravity keeps the planets in orbit around the sun and the stars and the stars in orbit around the center of the galaxy. Gravity also holds the stars together against their own internal pressure.
Did gravity form stars?
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.
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.
Does gravity depend on mass or weight?
Gravity depends on the mass of an object. Weight, on the other hand, is the force of gravity acting on an object's mass. So, weight depends on both an object's mass and the strength of gravity acting on it.
Why is the pressure extremely high for the nuclei to crash into one another in stars?
gravity acting on the mass of the star.
Can a object have weight without having mass?
No. Weight is the result of gravity acting on mass.
What forces act on nebula?
The main forces acting on a nebula are gravity, which causes the nebula to collapse and form stars, and radiation pressure, which can push material away from the forming stars. Additionally, magnetic fields can play a role in shaping the structure and dynamics of a nebula.
How does the size of an object affect the force of gravity acting upon it?
The force of gravity acting on an object is directly proportional to its mass. This means that the larger the object, the greater the force of gravity acting upon it.
Do stars twinkle due to refraction or gravity?
Stars in the universe twinkle because of refraction not gravity.
Are stars rounded by gravity?
yes because they levitate in space gravity does hold stars up
Measure of force of gravity acting in an object?
The measure of the force of gravity acting on an object is its weight. Weight is the force exerted by gravity on the mass of an object, and it is typically measured in units such as pounds or newtons. The weight of an object can vary depending on the strength of the gravitational field acting upon it.
How are stars made with no gravity?
They aren't. Stars form as a result of a cloud of gas collapsing due to gravity.
The force of gravity acting upon the mass of an object?
That's usually called the object's "weight". Like say if you're talking about the forces of gravity between you and the Earth, the force of gravity acting on you is your weight on the Earth, and the force of gravity acting on the Earth is the Earth's weight on you, and they're equal.
What is the amount of gravity acting an objects mass?
The amount of gravity acting on an object is determined by its mass. The greater the mass of the object, the stronger the force of gravity acting on it. Gravity is a force that pulls objects towards each other, with the strength of the force depending on the masses of the objects and the distance between them.
How does gravity affect the stars moon an planets?
Gravity keeps the planets in orbit around the sun and the stars and the stars in orbit around the center of the galaxy. Gravity also holds the stars together against their own internal pressure.
What is the force acting upon a projectile?
