What is the relation between escape velocity and orbital velocity of a satellite if the satellite is close to the earth?
The relation between escape velocity and orbital velocity are proportional.
What is the difference between escape velocity and orbital velocity of a satellite?
Orbital velocity is the speed required to achieve orbit around a celestial body, such as a planet or a star, while escape velocity is the speed required to leave that orbit.
How do you calculate the trajectory of a satellite?
As seen in the equation v = SQRT(G * Mcentral / R), the mass of the central body (earth) and the radius of the orbit affect orbital speed. The orbital radius is in turn dependent upon the height of the satellite above the earth.
What is orbital velocity and find the expression for orbital velocity?
V∘=√gR is called orbital velocity. Its value is 7.92 km/sec.
What is the relation between the escape velocity and orbital velocity?
The relationship between the escape velocity and the orbital velocity is defined by Ve = 2 Vo where Ve is the escape velocity and Vo is the orbital velocity. And the escape velocity is root-two times the orbit velocity.
What is orbital trajectory?
The terms trajectory and orbit both refer to the path of a body in space. Orbit is commonly used in connection with natural bodies (planets, moons, etc.) and is often associated with paths that are more or less indefinitely extended or of a repetitive character, like the orbit of the Moon around the Earth.
What is a satellite trajectory?
2.1 Definition of an Orbit and a Trajectory While a trajectory is a path traced by a moving body, an orbit is a trajectory that is periodically repeated. While the path followed by the motion of an artificial satellite around Earth is an orbit, the path followed by a launch vehicle is called the launch trajectory.
What is escape velocity derive an expression for the escape velocity of an object from the surface of earth?
The content below will help to derive an expression for escape velocity. The acceleration due to gravity (earth), g = 9.8 m/s2. The radius (earth), R = 6.4 × 106 m. The escape velocity (earth), ve = √2 × 9.8 × 6.4 × 106. Therefore, ve = 11.2 × 103 m/s = 11.186 km/s or 11.2 km/s (Approximately).
What is orbital velocity of a satellite?
The velocity which is required to keep the satellite revolves around its orbit is called orbital velocity of a satellite. It depends upon the radius of the orbit in which it revolves. Suppose a satellite of mass ‘m’ revolving around the earth at a height ‘h’ from the surface. Let v 0 be the orbital velocity of the satellite.
What happens if the escape velocity is less than the orbital?
If escape velocity is less than orbital then the orbit will diminish which will result in the object crashing. If it is more then the object will be free in the orbit and will likely float into space.
What type of elliptical orbits do artificial satellites follow?
The elliptical orbits generated by velocities below escape velocity are the type followed by artificial satellites, as well as by all the planets and moons of the solar system.
What is the difference between orbit and trajectory?
The terms trajectory and orbit both refer to the path of a body in space. Trajectory is commonly used in connection with projectiles and is often associated with paths of limited extent, i. e., paths having clearly identified initial and end points.
