The paper "Orbital Energy and Escape Velocity" is a perfect example of an assignment on environmental studies. Orbital Energy is a term related to astrophysics and refers to the dynamic energy of those celestial bodies that rotate on an orbit. Out of the three laws suggested by Kepler, the 2nd Law is the one that explains orbital energy. According to the 2nd Law framed by Kepler, the energy contained in any celestial body involved in an orbital spin could be considered as the sum of Kinetic Energy and Gravitational Potential Energy. Kinetic energy = 1 / 2 mv2 and Potential Energy = - Gm m / r Where m = momentum of the heavenly body.
V = velocity of the orbiting energy. R = Distance of the celestial body from the object around which it rotates. Hence, the formula for the orbital energy contained in any orbiting body is Energy = 1 / 2 mv2 - Gm m / r. The elements on earth are glued to its surface because of the inherent gravitational pull of the planet.
This pull is so intense that it is almost impossible for any object to move out of the earth atmosphere unless it does it with a great speed or rather a great velocity. A good example is that of the rockets and other man-made satellites which are sent to space using the logic of escape velocity. The average speed that any man-made object needs to move out of the earth orbit is as high as 25000 miles per 7 seconds. This is the value of escape velocity (Anonymous, Space Environment, n.d. )
