To orbit around Earth, the centripetal force of the object must equal the gravitational force. Therefore: mv2/r = GMm/r2 v2 = GM/r v = sqrt(GM/r) Plug in G: universal gravitational constant (6.67*10-11 Nm2/kg2), M: mass of Earth (5.97*1024 kg), and r: radius of orbit as measured from Earth's centre (e.g. 1000 km above the ground would correspond to an r of 1000 km + radius of the Earth (6367.5 km = 7367.5 km = 7367500 m)
What else can I help you with?
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 is the shape of the orbit when the velocity of the satellite is everywhere perpendicular to the force of gravity?
If the velocity of the satellite is always perpendicular to the force of gravity, then the eccentricity of the orbit is zero, and it's perfectly circular.
Can a rocket traveling at orbital velocity reach the moon?
Yes, but it has to be travelling at the MOON'S orbital velocity, which is quite a bit more than that needed for low earth or even geosynchronous orbit. The faster one goes, the higher the orbit.
Is the critical velocity equal to orbital velocity of satellite?
Balance of force of gravity by centripetal forceYes, for any given orbital radius (r) only one velocity will give stable orbit, this is called the critical velocity.Pick your orbital radius and satellite mass (m)Use Gmm / r2 to calculate gravitational force (f),then find velocity from : v = sq root ( (r * f ) / m)
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.
Is orbital velocity the velocity a rocket must reach to fly off into space?

What does the term 'escape velocity' mean?
Escape velocity is the minimum velocity needed for an object to break free from the gravitational pull of a celestial body, such as a planet or moon. It allows an object to overcome gravity and travel into space without being pulled back. The specific escape velocity depends on the mass and radius of the celestial body.

If the velocity of the satellite is always perpendicular to the force of gravity, then the eccentricity of the orbit is zero, and it's perfectly circular.

How much energy is needed to put something into orbit?
The energy required to put an object into orbit depends on its mass and the altitude of the desired orbit. Generally, it takes about 9.81 MJ/kg (megajoules per kilogram) for low Earth orbit, factoring in both the gravitational potential energy and the kinetic energy needed to achieve orbital velocity. For example, launching a 1,000 kg satellite into low Earth orbit would require approximately 9.81 GJ (gigajoules) of energy, not including additional energy needed for atmospheric drag and other losses during launch.
What is needed to launch anything or anyone into orbit?
To date rockets are the only method that can be used to put something or someone into orbit.
Is escape velocity bigger than orbital velocity?
Yes, escape velocity is greater than orbital velocity. Escape velocity is the minimum speed required for an object to break free from the gravitational pull of a celestial body and move into space. Orbital velocity is the speed required for an object to maintain a stable orbit around a celestial body.
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.
What direction of the velocity causes a circular orbit?
The velocity in a circular orbit changes all the time. The acceleration is towards the center.
The velocity a rocket must reach to establish an orbit in space is?
The velocity a rocket must reach to establish an orbit in space is called orbital velocity. It depends on the altitude of the desired orbit and the mass of the body being orbited. In general, orbital velocity is around 28,000 km/h for low Earth orbit.
