How much energy is needed to put something into orbit?
The energy required to put an object into orbit depends on its mass and the altitude of the desired orbit. Generally, it takes about 9.81 MJ/kg (megajoules per kilogram) for low Earth orbit, factoring in both the gravitational potential energy and the kinetic energy needed to achieve orbital velocity. For example, launching a 1,000 kg satellite into low Earth orbit would require approximately 9.81 GJ (gigajoules) of energy, not including additional energy needed for atmospheric drag and other losses during launch.
Where does a satellite in elliptical orbit have its greatest total energy?
In an elliptical orbit, a satellite has its greatest total energy at the point known as apogee, which is the farthest point from the central body it is orbiting. Total energy in an orbital system is the sum of kinetic and potential energy, and at apogee, the satellite's potential energy is maximized due to its distance from the central body. However, it's important to note that total energy remains constant throughout the orbit; it is the distribution between kinetic and potential energy that changes.
Which planet has most elliptical orbit?
Mercury has the most elliptical orbit among the planets in our solar system. Its orbit is significantly elongated, with the eccentricity of 0.2056, which means that it deviates the most from a perfect circle compared to other planets.
What two things does the sun provide for earth?
Location (orbit) and energy.
What effects does gravity have on planets orbit?
Gravity, together with the planet's total kinetic and potential energy, completely determines the size and shape of the orbit.
What orbits in layers in the atom?
Electrons with different energy levels orbit in the different shells of the atom. The electrons located in the outer shell are called valence electrons, they have the most energy and are the ones who participate most in bonding.
Is electron emits energy when it revolves in quantized orbit?
No. A quantized orbit means the energy is locked in as a constant. It would have to switch to a different orbit to emit energy.
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.)
Where does a comet have the most potential energy?
A comet has the most potential energy at its farthest point from the sun (aphelion) in its elliptical orbit. At this point, the comet's gravitational potential energy is maximized due to the distance from the sun being at its greatest.
What are two features of the modern model of the atom?
energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.
What happens to the energy of the electrons in the orbits as the radius of each orbit increases?
What happens to the energy of the electrons in the orbits of each orbit increases
What is orbital energy of an orbiting object?
Orbital energy is the total energy of an object in orbit, which is the sum of its kinetic energy (due to its motion) and its gravitational potential energy (due to its position in the gravitational field of another body). This energy determines the object's orbit shape and stability.
How do element become stable?
The elements can only be stable when it complete is octate in its outer most orbit has 8 electrons in its outer most orbit by gaining or losing energy
What do you mean by the orbital energy of an orbiting object?
Orbital energy is the sum of an object's kinetic energy and gravitational potential energy while it is in orbit around another object, such as a planet or a star. It dictates the object's total energy in that orbit and is crucial for understanding its motion and stability in space.
Is it possible for electrons to orbit the nucleus with any possible energy?
No. Electrons will orbit around an atom only at specific energies (which change depending on the atom's atomic number and atomic mass). If you try to use a photon to change the energy of an electron and move it to another orbit path (or "energy level"), and the photon has the wrong energy in it, the electron won't change its orbit.
Where is the potential energy of a spacecraft greater?
in orbit.
How many electrons does a neutral atom of oxygen O usually have in its outer orbit?
A neutral atom of oxygen has 6 electrons in it's most outer orbit. Generally, if you count horizontally from left-to-right on the periodic table, you get the number of electrons in its' most outer orbit. You start every row with 1, of course. :) Hope that helps!
