Orbital 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.

Difference between probes and satellites regarding orbital and escape velocity?

a probe need to travel escape velocity while a satellite travel orbital velocity.

What is the fifferce between orbital and escape 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.

How is orbital velocity and escape velocity different?

I believe orbital velocity is about 73% of escape velocity at the same distance from the mass center of the body being orbited. Could be 71% because escape velocity divided by the square root of 2 seemed to be indicated.

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

Compare orbital and escape velocity?

Orbital velocity vo= v sqrt(1 + e) where e is the eccentricity of the orbit and e<1. Escape velocity is when e=1, ve=vsqrt(2).

What is the minimum velocity needed to place something into orbit?

Orbital velocity can be approximated with Vo ~= (GM/r) 0.5 Vo ~= VE/1.414 where G is the gravitational constant, M is the mass of the main body, with the mass of the second body being negligible, r being the distance between them, and alternatively, VE being the escape velocity. Using the second form, based on escape velocity, the orbital velocity of a satellite around the Earth is 11.186 / 1.414 = 7.9 km s-1.

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.

Why the moon does not escape from the earth?

They orbit around their common centre of gravity, the orbital radius and velocity of both (centripital force) is exactly enough to overcome the force of gravity between them.

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.

Define escape velocity?

Escape velocity is the velocity needed to escape the gravitational pull of a body. The escape velocity of the Earth is about 7 miles per second. The escape velocity of the Sun is about 25 miles per second.

What is the relationship between escape velocity black holes and 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 the escape velocity of Uranus?

Uranus has an escape velocity of 21.3 km/s. For comparison the Earth has an escape velocity of 11.186 km/s

What is the escape velocity of the asteroid belt?

What does the term 'escape velocity' mean?

Escape velocity is the minimum velocity (or speed) that an object would need to reach to 'escape' the orbit of a planet.

What is mercury's escape velocity?

The planet Mercury's escape velocity is 4.3 kilometers per second. The escape velocity of the Earth is 11.2 kilometers per second.

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 happens if a projectile has a velocity greater than escape velocity?

In that case, it will be able to escape from Earth's gravity forever (assuming the escape velocity refers to Earth).

How do you find 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
