Explain What is the Orbital Energy and what is the Escape Velocity?

Orbital energy is that amount of energy to keep a spacecraft or satellite in orbit around the earth. If the object fails to maintain this amount of energy, its orbit will get smaller and smaller until the object falls to earth. Escape velocity is that amount of speed required for an object to escape the earth's gravitational hold. Notice how you can't jump into outer space. It's because your legs can't produce enough power to achieve escape velocity.

∙ 14y agoOrbital velocity is the speed an object revolves around another object - Earth revolving around the Sun.
Escape velocity is the speed required to break away from an objects gravitational attraction - Eg a space craft leaving Earth.

The velocity a rocket must reach to establish an orbit around earth is called?
Orbital velocity, or Close orbital velocity.
There is no atmosphere on the moon. Explain on the basis of escape velocity?
the escape velocity of moon is less than that of earth...so the gas easily escape out and hence moon has no atmosphere..
Is orbital velocity the velocity a rocket must reach to fly off into space?
No.Orbital Velocity is the velocity required by a body to achieve a circular orbit around its primary.Escape velocity is the minimum velocity needed to escape a gravitational field
What speed does a rocket have to reach to get into space?
(Escape velocity) at least 7 miles ber second. Close-Orbital velocity is about 5 miles per second.
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.

Difference between probes and satellites regarding orbital and escape velocity?
a probe need to travel escape velocity while a satellite travel orbital velocity.
Is escape velocity bigger than orbital velocity?
Yes.
What is the difference between escape velocity and orbital velocity?
Escape velocity is the velocity that an object needs in order to reach infinite distance, wherein the force will equal to zero. Orbital velocity is the velocity of an object so it can stay in orbit.
What is the difference between a satellite and a probe with regard to orbital velocity and escape velocity?
Well, a satellite revolves about 80 times faster than the probe. The probe masters different situations which cause orbital problems. Escape velocity doesn't have the power that regards to the probe. Scientists assume that the satellite has the power, but others don't. The probe connects to orbital velocity and has the power to control it.
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).

The speed and direction a rocket must travel to break away from a planet's gravitational pull is called?
To escape the gravitation pull of an object you must travel at or in excess of the escape velocity. The direction of the escape velocity is always radially outward from the center of the object.

Why velocity is double during circular motion?
This is called the law of astronomic diversion. Gaining energy from falling: half of the energy is diverted and half is potentionally gained. Yet the astronomical law is that falling to a gravitational centrum: half of the gained energy is given to the surroundings ( in form of heat or other) and half of it is gained as potential mechanical Galileian/Newtonian energy. So: a=v^2/r is the changement to velocity = versnelling per radius If a= gM/r then object resides. The free area for energy is from half escape velocity to a full escape velocity for molecules. Hidrogen escapes (while escape velocity earth= 11 km / sec)
