What is Rocket speed per sec to escape from earth gravity?
the rocket speed required to escape out of the earth's gravity is known as escape velocity which is numerically equal to 11.2 km per sec.
What is te Formula of escape velocity?
Escape velocity is given by. √2gR or √2GM/R .therefore escape velocity is directly prop. to gravity of a planet or star or any other body. More is the gravity more is the escape velocity. The escape velocity of our earth is 11.2 km/s and that of moon is 2.31 km/s
What does distance times velocity or time equal?
it = speed over time
What are the similarities between speed and acceleration?
The two words are synonyms. However, in physics there is a more precise definition, which is a change in an object's position in a specified direction with time. So in everyday language we could say the speed of the car is 60 miles per hour, but in physics you'd say its velocity is 60 miles per hour North/South/East/West.
What do you mean when we talk about a constant speed?
No. Circular motion can have constant speed but varying velocity. Constant speed means constant speed in any direction, like a car on cruise control turning a corner. Constant velocity means constant speed in a straight line. If the direction changes, that's considered a change in velocity.
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 is escape velocity of speed?
You mean what is the escape velocity of Earth? If so, the answer is 11,2 km/s
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.
How much speed required to go against gravity?
Assuming there is no air resistance, if an object starts at a speed of 11.2 km/sec, it can escape the gravitational field of Earth. This "escape velocity" is different for different planets, moons, etc.Assuming there is no air resistance, if an object starts at a speed of 11.2 km/sec, it can escape the gravitational field of Earth.

Can an intercontinental ballistic missile reach escape velocity?
Yes. Probes have already be sent to the Moon, and other planets; this requires a velocity very near the escape velocity from Earth. Other probes are leaving the Solar System, so they achieved the much higher escape velocity required to escape the attraction from the Sun.
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.
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?
