What reason do black holes draw other nearby space objects to them?
Black holes draw in other matter due to the huge gravitational pull they exert. Because of this, even light cannot escape a black hole's pull.
Which object in our solour system has the biggest gravitational pull and why?
In our solar system it would be the sun. But there are much more massive objects beyond our solar sytem that would have a higher pull - the more massive an object is the higher its gravitational pull. a black hole has a huge gravitational pull, so strong that light cannot escape.
Why do gases escape Mercury easily?
The solar winds from the Sun, because Mercury is so close, blow the atmosphere away. Therefore, all of the gases it has are from the Sun because the solar winds are constantly replacing Mercury's atmosphere.
Could the reason that objects including light can't escape a black hole be the same reason they can't escape tornadoes?
AnswerA powerful torch lit inside a tornado might be visible to someone observing it from a safe distance, but dust and debris would likely absorb most if not all of its light. However a torch dropped into a black hole would completely disappear from view, not only because it would be completely and utterly destroyed, but also because the light leaving it would not be allowed to escape by the immense gravitational force of the black hole.
Does the escape velocity on a planet depend upon its density or mass?
No, its depends on the planets gravitational pull
How do objects escape from a black hole?
Objects cannot escape from a black hole because the gravitational pull is so strong that not even light can escape.
What is a star in which light cannot escape because of the immense gravitational pull at its surface called?
A star in which light cannot escape because of its immense gravitational pull at its surface is called a black hole.
What are objects from which light cannot escape because of the immense gravitatonal pull at its surface called?
They are called black holes. Their gravitational pull is so strong that not even light can escape from them, leading to them being invisible and appearing as "black" in space.
Why does an object orbit something?
Objects orbit because they are moving too quickly for gravity to pull them down, but not quickly enough to escape the gravitational pull.
What is the escape speed from the surface of the earth?
The escape speed from the surface of the Earth is about 11.2 kilometers per second (about 25,000 miles per hour). This is the speed at which an object must travel to break free from the Earth's gravitational pull and not fall back down.
How black can black get?
Perfect black would be the inability for any light at all to reflect off the surface. A black hole is black because light cannot escape the gravitational pull.
Ignoring air resistance what is the minimum initial speed a projectile must have at the Earths surface if the projectile is to escape the Earths gravitational pull?
The minimum initial speed for a projectile to escape Earth's gravitational pull (escape velocity) is about 11.2 km/s. This speed is independent of the mass of the projectile and is based on the balance between the projectile's kinetic energy and gravitational potential energy. Any speed greater than the escape velocity will allow the projectile to escape Earth's gravitational pull.
You say that the escape velocity is the one required to escape the earth's gravitational speed then we say the satellites stay in orbits because of the earth's gravitational speed how does that ha?
Satellites are traveling at less than escape velocity. (roughly, orbital velocity is about 7 tenths of escape).
Which objects in space emits no light?
black hole as they have a very powerful gravitational pull such that even light could not escape its gravity and fall into it
What reason do black holes draw other nearby space objects to them?
Black holes draw in other matter due to the huge gravitational pull they exert. Because of this, even light cannot escape a black hole's pull.
How is the escape velocity equation derived?
The escape velocity equation is derived by setting the kinetic energy of an object equal to the gravitational potential energy at the surface of a planet. By equating these two energies, we can solve for the velocity needed for an object to escape the planet's gravitational pull. The equation is derived using principles of energy conservation and Newton's laws of motion.
What is the gravitational force of black holes?
The gravitational force of black holes is extremely strong due to their immense mass and density. This force is so powerful that not even light can escape from a black hole's gravitational pull, making them some of the most mysterious and fascinating objects in the universe.
