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


The velocity a rocket must reach to establish an orbit around earth is called?

The velocity a rocket must reach to establish an orbit around the Earth is called orbital velocity. It is the speed required for an object to overcome gravitational pull and maintain a stable orbit around the planet. The orbital velocity depends on the altitude of the orbit and follows Kepler's laws of planetary motion.


How does the magnitude of the velocity affect a planet's orbit?

The magnitude of a planet's velocity affects the shape and size of its orbit. A higher velocity can cause a planet to move in a more elongated elliptical orbit, while a lower velocity can result in a more circular orbit. The velocity also influences the planet's escape velocity, which determines if it can break free from its orbit.


If a body falls freely from infinity then it will be striking the earth with what velocity?

The body will be striking the Earth with a velocity equal to its escape velocity, which is around 11.2 km/s. At this velocity, the body will have enough kinetic energy to overcome the gravitational pull of the Earth and reach the surface.


What would be the effect on the orbital velocity of satellite if mass of satellite is double?

Doubling the mass of a satellite would result in no change in its orbital velocity. This is because the orbital velocity of a satellite only depends on the mass of the planet it is orbiting and the radius of its orbit, but not on the satellite's own mass.
