PHYIC CALCULATOR Orbital Velocity Calculator A precise tool.
📖
What is the Orbital Velocity Calculator & How does it work?
Orbital velocity is the speed at which a celestial body, such as a planet or satellite, moves around another body in a circular orbit. This velocity is crucial for maintaining the balance between the gravitational pull of the central body and the centrifugal force exerted by the orbiting body.
The formula to calculate orbital velocity (v) is given by:
[ v = sqrt{frac{G cdot M}{r}} ]
v = orbital velocity
G = gravitational constant (approximately 6.67430 (times) 10-11 m3 kg-1 s-2)
M = mass of the central body (in kilograms)
r = orbital radius (in meters)

Frequently Asked Questions
What is orbital velocity?
Orbital velocity is the speed at which a planet or satellite moves in a circular orbit around another body.
How do I calculate orbital velocity?
Use the formula v = sqrt(G * M / r), where G is the gravitational constant, M is the mass of the central body, and r is the radius of the orbit.
What is the gravitational constant (G)?
The gravitational constant (G) is approximately 6.67430 × 10^-11 m^3 kg^-1 s^-2.
Why is orbital velocity important?
Orbital velocity is crucial for understanding the balance between gravitational pull and centrifugal force in celestial mechanics.
Can this calculator be used for any celestial body?
Yes, you can use this calculator to find the orbital velocity of planets, moons, or artificial satellites around their respective central bodies.
What units should I use for mass and radius in the formula?
Use kilograms (kg) for mass and meters (m) for radius when calculating orbital velocity.
How does changing the radius affect orbital velocity?
Increasing the radius of the orbit decreases the orbital velocity, while decreasing the radius increases it.
