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.
The velocity a rocket must reach to establish an orbit around earth is called?
Orbital velocity, or Close orbital velocity.
A body falling freely from a height towared the earth moves with uniform?
... accelerates at approx 9.81 metres per second squared and experiences weightlessness. Friction with the air prevents continuous acceleration and the falling body reaches a maximum velocity called the terminal velocity.
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.
When is the earth orbital velocity the fastest?
perihelion
How do you explain the effects of the sunlight striking earth?
explain the effects of the sunlight striking earth
What is the final velocity of a freely falling object?
The final speed of an object in free fall is known as terminal velocity. Terminal velocity on Earth can range from 54 meters per second (in SI units) to 90 meters per second based on aerodynamics.

Whats the height of sky from earth?
infinity
The tangential velocity of an Earth satellite is its velocity?
parallel to the surface of the Earth
What is the largest velocity reached by falling object?
The escape velocity from Earth is 11.2 kilometers/second. This is also the speed that an object would reach if it fell onto Earth's surface from far, far away ("infinity" is often used, to simplify calculations) - without air resistance, and without interference by other objects that might also attract it.The escape velocity from Earth is 11.2 kilometers/second.

What is the excape velocity on earth?
For the Earth, escape velocity is approximately 25,000 MPH.
How many games are on the Earth?
infinity
What is true about an objects fall velocity as it approaches the earth's surface?
The velocity increases as it approaches the earth.
How motion of satellite similar to the motion of an object in freefall?
A satellite is in free fall. When the only force acting upon it is gravity, it reacts freely to this gravity, accelerating towards Earth. That is to say, instead of going in a straight line, the velocity vector changes direction, towards Earth. If the satellite is fast enough to be in orbit, it will never actually fall on Earth; but the velocity vector changes all the time.
What is the velocity of earth in meters per second?
Earth's velocity through space is 297,800 m/s
Can you consider earth as having a uniform velocity?
No. Earth's rotational velocity is slowing. Do you mean the velocity of Earth's revolution around the sun? The earth speeds up in its orbit until it reaches perihelion, and then slows until it reaches aphelion.
