How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
What is escape volocity?
Escape velocity is the speed you would have to go to escape gravity.
What is the escape speed from the surface of the earth?
The escape speed from the surface of the earth, or the "escape velocity" from the earth is about 11.2km/s.
Why you must study escape velocity?
You don't. "Escape velocity" is a meaningless number. "Escape velocity" is the speed at which a CANNON SHELL must be fired in order to escape from the Earth's gravity well. With a powered rocket, you can "escape" from the Earth's gravity at ANY speed - as long as you have enough fuel.
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).
What height will it gain after the escape velocity becomes half?
That will depend not only on the escape velocity, but also - very importantly - on the object's speed.
Escape velocity is the speed required to?
escape the gravitational well and if the planetoid has one, the atmosphere.
To escape from a planet's an object muct reach a speed called the?
That would be its escape velocity.
To escape from a planets gravity an object must reach a speed called the?
Escape Velocity
How are the mass of the body and escape speed related?
The greater the mass of the planet, the greater will be the escape velocity.
Is escape velocity of light infinity?
Not at all. It would take an infinitely large mass to produce an infinite escape velocity, and no such infinite mass exists. Furthermore, the escape velocity for any object is the same no matter what is trying to escape, so light does not have its own escape velocity. This question presumably concerns black holes. Light does not escape from black holes because the escape velocity is greater than the speed of light. The speed of light is not infinite, it is 300,000 kilometers per second.
What does the term 'escape velocity' mean?
Escape velocity is what a moving body has to achieve in order not to be pulled back down to the planet. For Earth it is about 7 miles per second.
