Orbital velocity, escape velocity

Introduction Terminal velocity is the velocity that is achieved by an item when it falls through the air. The item holds no acceleration since the net force acting on the item is zero. Terminal velocity can also be defined as the consistent speed accomplished by an item that is openly falling through a gas or […]

Introduction Orbital Velocity can be defined as the speed at which a celestial body, mainly a satellite, revolves around the orbit of another celestial body. The satellite revolves around a celestial body always greater in mass than the satellite. The Formula: The orbital velocity formula for any revolving object is given by, Where, Vorbit=GMR G

Hohmann Transfer orbit is an elliptical orbit in orbit mechanism used to transfer between two circular orbitals with different radii around a central body in the same plane. The plane in such a case is usually tangential to both.  A low amount or a less amount of propellant can be used to travel by the

Although the phrase “escape velocity” is commonly used, it is more appropriately described as a speed rather than a velocity because it is directionless; the escape speed increases with the primary body’s mass and decreases with distance from the primary body. The object’s escape speed is thus determined by how far it has already travelled,

Concept of Escape velocity When standing on Earth, if we throw any object up, it comes back to us. Have you ever wondered why it does come back to us and doesn’t leave the surface of the earth? The possible reason is the backward pull exerting on it. The backward pull exerted by the surface

Introduction Escape velocity is the speed required for a body to escape the gravitational field or gravitational centre of attraction without the need for additional velocity or acceleration. The escape velocity reduces with altitude. In other words, escape velocity can be defined as the minimum velocity a body must have to escape the gravitational attraction
