Orbital Velocity Derivation. Orbital velocity is defined as the minimum velocity a body must maintain to stay in orbit. Due to the inertia of the moving body, the body has a tendency to move on in a straight line. But, the gravitational force tends to pull it down.

The orbital velocity equation is given by: \[\Rightarrow v = \sqrt{\frac{GM}{r}}\] Where, R is the radius of the orbit, M is the mass of the central body of attraction, G is the gravitational constant. The orbital velocity can be calculated for any satellite and the consequent planet if the mass and radii are known.
The following steps can be followed to derive an expression for the orbital velocity of a satellite revolving in an orbit. For orbital speed derivation, both the gravitational force and centripetal force are very important. Gravitational force (Fg) is the force exerted by the body at the center to keep the satellite in its orbit. Centripetal force ...
Escape velocity is the base speed required for a free, non-propelled object to escape from the gravitational impact of a huge center body, that is, to move an unlimited distance from it. This velocity is a component of the mass of the body and separation to the focal point of mass of the body. To find the difference between escape velocity and orbi...
We all know about gravitational force. To reach space, the satellite should be able to overcome this pull. And thus it needs to have a specific velocity called escape velocity to reach the distance it intends to. Lower velocity is needed if the distance from the primary body; in our case, it is the earth, higher the distance. So that is why the com...
We already have a brief idea about black holes. For anything that is near the black holeis taken inside. And the escape velocity for something that enters a black hole is nearly more than the speed of the light. However, there are black holes that are formed at the center of galaxies ejecting the matter absorbed in the speed of the light. They are ...

M = mass of the body at center, R = radius of orbit. In most of the cases M is the weight of the earth. It’s derivation is explained in the figure below, Solved Examples for Orbital Velocity Formula. Q: A satellite launch is made for the study of Jupiter.Determine its velocity around Jupiter. Given: Radius of Jupiter R = 70.5 × 106 m,
The orbital speed of the body which is generally a planet or a natural satellite is the speed at which it orbits around the center of the system. This topic will explain the concept of it with orbital speed formula.
May 31, 2023 · The formula for orbital velocity is derived using the centripetal force and the gravitational force on the object. The formula for the orbital velocity of any satellite revolving around the Earth is mathematically stated as \(v_{orbit} = \sqrt{\frac{GM_{E}}{r}}\) Where, G = Gravitational constant of the Earth \(M_E\) = Mass of the Earth
Jul 20, 2022 · The derivation of Equation (25.A.9) in the form \[u=\frac{1}{r_{0}}(1-\varepsilon \cos \theta) \nonumber \] suggests that the equation of motion for the one-body problem might be manipulated to obtain a simple differential equation.
Equation of orbit: \[ \begin{aligned} r(\phi) = \frac{c}{1 + \epsilon \cos \phi}. \end{aligned} \] Orbital speed: \[ \begin{aligned} v(\phi) = \sqrt{\frac{\gamma}{\mu c}} \sqrt{ \frac{c^2}{r^2} + \epsilon^2 \sin^2 \phi} \\ \approx \sqrt{\frac{GM}{c}} \sqrt{\frac{c^2}{r^2} + \epsilon^2 \sin^2 \phi}. \end{aligned} \] Orbital energy:
