What may happen to a rocket which rises from the earth never attains escape velocity?
A rocket that doesn't reach "escape velocity" will be overcome by gravity and will be pulled back down to Earth. Also, rockets which go into orbit have not reached escape velocity. Escape velocity is what is needed to completely leave earth's gravity well.
Starship A weighs 2 tons and requires a speed of about 11 km s to escape from the Earth The escape velocity from Earth of Starship B that weighs 4 tons is?
The escape velocity of an object only depends on the mass of the planet it is escaping from, not the mass of the object itself. Therefore, Starship B would also require a speed of about 11 km/s to escape from Earth.
A rocket that moves upward from earth's surface at escape velocity will?
Escape the earth's gravitational pull and continue out into space. However, a rocket does not need to be launched at the escape velocity as it can continue to accelerate as it climbs. A gun projectile would need to be fired with the escape velocity. In a perfect system with only the projectile and the Earth: If the projectile is fired with the exact escape velocity it will travel to infinity away from the Earth. Upon reaching infinitely far away from Earth the projectile would have zero velocity. All of its kinetic energy (movement) would be transferred to potential energy.
How using Earth's rotation speed to escape gravity?
Earth's rotation speed doesn't affect the ability to escape Earth's gravity. Escaping Earth's gravity requires reaching a velocity of about 11.2 km/s regardless of Earth's rotation speed. Earth's rotation does provide a slight boost to the velocity required to escape in the direction of the rotation.
What is the escape velocity of the Sun in miles per hour?
The escape velocity of our sun is nearly 1.4 million mph(1,381,755.55 mph), about 55 times greater than Earth's.
What is the approximate escape velocity for the earth?
11.3 km/s or 7 m/s or 25000 mph
Is the escape velocity from the center of the earth different from the escape velocity from Earth's orbit?
Yes, very much so.
What is escape velocity of speed?
You mean what is the escape velocity of Earth? If so, the answer is 11,2 km/s
Is escape velocity same for all objects?
Yes. It is different for different planets etc. Escape velocity on earth is different than escape velocity on Jupiter.
What is velocity that a rocket must attain to escape the force of gravity on earth?
The velocity of a any object to surpass the gravity of earth commonly known as escape velocity is 11.2Km/s.
What is the excape velocity on earth?
The escape velocity on Earth is approximately 11.2 kilometers per second (33 times the speed of sound). This is the speed required for an object to break free from Earth's gravitational pull and escape into space.
Escape velocity of earth versus escape velocity on Uranus?
EV on Earth is 11.186 km/s EV on Uranus is 21.3 km/s
What is anEscape Velocity?
Velocity sufficient for a body to escape from a gravitational attraction without acceleration. Earth has an escape velocity of 11.19 kmsec-1 .
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).
Is the escape velocity higher for the earth or the moon?
The mass of an object is the same wherever it may be. The weight of an object changes however. The weight of an object is the product of its mass times gravity. Gravity is greater on earth than it is on the moon, so an object will weigh more on earth.
What is the escape velocity from the earth surface?
12km/Sec
What may happen to a rocket which rises from the earth never attains escape velocity?
A rocket that doesn't reach "escape velocity" will be overcome by gravity and will be pulled back down to Earth. Also, rockets which go into orbit have not reached escape velocity. Escape velocity is what is needed to completely leave earth's gravity well.
