if i want to find the supplied energy when the satelite's orbit changed, do i need to find the its velocity or only find its K.E. ??
thanks..
thanks..
Why don't you explain the problem you are trying to solve? A satellite in orbit has a certain total energy, which depends on the radius of the orbit. To change the orbit, you must add or subtract energy.Originally posted by jazzchan
would u mind to tell me more ??
Satellites may need to change their orbit for various reasons, such as avoiding collisions with other objects in space or adjusting their position for optimal communication or observational purposes. The frequency of orbit changes varies depending on the specific mission and objectives of the satellite, but it can range from every few days to several years.
Several factors can influence the need for a satellite to change its orbit, including changes in the Earth's gravitational pull, the presence of space debris, and the effects of solar radiation. Additionally, the purpose of the satellite and its desired position in relation to other objects in space can also determine the need for an orbit change.
The orbit of a satellite can be changed through the use of thrusters or engines that provide thrust in a specific direction. This thrust can be used to accelerate or decelerate the satellite, altering its velocity and changing its orbit. The amount of thrust and direction of the force applied will determine the magnitude and direction of the orbit change.
Yes, a satellite's orbit can be changed multiple times throughout its mission. In fact, many satellites have the capability to make small adjustments to their orbit regularly in order to maintain their desired position and trajectory. However, frequent orbit changes can also consume a significant amount of a satellite's fuel and may limit its overall operational lifespan.
After a satellite's orbit is changed, its previous orbit will remain in space until it is affected by other gravitational forces or collisions with other objects. In some cases, satellites may be intentionally directed towards the Earth's atmosphere to burn up upon re-entry, which can help to prevent space debris and potential hazards for other spacecraft.
