The potential energy of a satellite in orbit around a planet is due to the gravitational attraction between the satellite and the planet. It is a type of energy that depends on the satellite's position relative to the planet, and is higher the higher the satellite is from the planet's surface. Mathematically, the potential energy of a satellite can be calculated using the formula: PE = - G * (m1 * m2) / r, where G is the gravitational constant, m1 and m2 are the masses of the planet and satellite, and r is the distance between their centers.
What else can I help you with?
A satellite falling to the earth has kentic energy of 182.2 billon Joules and a potential energy of 1.6 billion JoulesWhat is its mechanical energy?
The mechanical energy of the satellite is the sum of its kinetic energy and potential energy. In this case, the mechanical energy would be 182.2 billion Joules (kinetic energy) plus 1.6 billion Joules (potential energy), totaling 183.8 billion Joules.
Where is gravitational potential energy found?
Gravitational potential energy is found in objects that are lifted above the ground, such as a book on a shelf or a satellite in space. It represents the energy stored in an object due to its position in a gravitational field.
What are the examples of gravity potential energy?
Well, we know gravity is the pull on an object. Also, that potential energy is when an object is at the highest point. So, some examples of this would be when a roller coaster is at the very top, it is when it has the most potential energy, and gravity is pulling upon it.
What is the opposite of kinetic?
Normally, in most contexts, the opposite of "kinetic" (moving) could be "static" (not moving). When talking about 'energy' the opposite of "kinetic" can be "potential", i.e., kinetic energy vs potential energy. An object in ballistic motion (i.e., moving only under the influence of a simple gravitational field) may exchange its energy between kinetic and potential forms, perhaps even repeatedly, but the sum of the two will remain constant. Examples (neglecting friction) include a pendulum, a roller coaster and a satellite in an elliptical orbit.
What factor affects potential energy?
The equation for Potential Energy isU=mghWhere:U=Potential energym= MassG= acceleration due to gravity which is 9.81m/s/s on Earthh= heightTherefore, the factors that affect potential energy are mass and height. Technically also gravity but if the experiment is carried out on the same planet, satellite etc then it should be constant.
The potential energy of a satellite in an elliptical orbit is?
The total energy of a satellite doesn't change. At its closest approach to the planet, it has the most kinetic energy and the least potential, whereas at its furthest retreat from the planet, it has the least kinetic energy and the most potential. But their sum ... the satellite's total mechanical energy ... is always the same. (It may gain heat energy when the sun is shining directly on it, and lose it when it's in the planet's cold shadow, but neither of those changes affects its orbit.)

At what height from the surface of the earth the total energy of the satellite is equal to its potential energy at a height of 2R from the surface of earth?
This question cannot be answered because:the total energy of the satellite includes its kinetic energy and that depends on its orbital speed. This is not specified;it is not clear what you mean by "potational": is it a typo for rotational or potential?what is R? The radius of the earth or the height of the satellite or some other measure?
Why a satellite is to be transferred to an orbit of larger radius energy is to be supplied to the satellite?
Object further away from gravitation center has higher potential energy. Therefore work(energy expense) must be done to put it there.
Does an object with high gravitational potential energy always have a low kinetic energy?
No. For example, a satellite in orbit has a lot of both.
Where is gravitational potential energy found?
Gravitational potential energy is found in objects that are lifted above the ground, such as a book on a shelf or a satellite in space. It represents the energy stored in an object due to its position in a gravitational field.
Which physical quantity is conserved of an earth satellite?
Velocity of satellite and hence its linear momentum changes continuously due to the change in the direction of motion in a circular orbit. However, angular momentum is conserved as no external torque acts on the satellite.
Where does a satellite in elliptical motion have the most kinetic energy?
At apapsis - when it is closest to the planet. In that case, it is moving fastest. Note that at apapsis, its potential energy will be lowest, since it is closer to the planet, while its kinetic energy will be highest. The sum of potential + kinetic energy doesn't change during the orbit.
What are the potential problems with satellite television?
Some of the potential problems with satellite television is the high cost and too many channels.
What are the examples of gravity potential energy?
Well, we know gravity is the pull on an object. Also, that potential energy is when an object is at the highest point. So, some examples of this would be when a roller coaster is at the very top, it is when it has the most potential energy, and gravity is pulling upon it.
Does a satellite use light energy?
Of course it uses solar energy. There are solar panels in a satellite.
