What is gravitational Energy? Is it a new concept? What is the relationship between gravitating objects and their respective clocks?
Gravitation is nothing but a ‘push/pull’ which compel the matter that moves through it to move with it. Thus, it may be said that the gravitational potential energy is the product of the force of gravity and the time evolution of the object in terms of its speed at rest. In simple terms, users can generate, manipulate and shape the gravitational potential energy, i.e. the energy that a body with weight mass has relative to another massive object under constant acceleration.
The gravitational energy may be defined as the amount of energy that would be required to accelerate the body of an object ‘without pushing it out of the cubic space time’. The gravitational force increases with the square of the distance from the source. Thus, for example, if we take the apple of our hand, its gravitational potential energy is plotted as plotted in figure 3. The distance of the apple (in inches) is plotted against time (in seconds). The value plotted against time (in seconds) is known as the gravitational potential energy of the apple.
Though most people understand the idea behind gravitational potential energy, but are not able to translate this understanding into a practical application. To understand why it is important to conserve energy, it is important to first understand what is meant by the conservation of gravitational potential energy. The conservation of energy implies that energy cannot be created or destroyed. However, it also means that the sources of such energy must be available for consumption.
As discussed above, the gravitational potential energy can be used as energy stored in some form to increase the height of some objects. The concept of gravitational potential energy is often explained in terms of a spring. The two major laws that govern this energy are known as the Law of Conservation of Energy and the Law of Conservation of Water. According to these laws, energy stored in any substance can be converted to kinetic energy when the substance moves.
The law of conservation of energy states that: force or motion is conserved only if it is caused by something that is moved from a point in which the source is located; and, only if the force can be transmitted from a point on the surface of the earth to some other point in the universe. Let us take an example of a jumping rocket. Its launch angle with respect to the horizontal axis of the earth is given by its horizontal position and its vertical position with respect to the vertical axis.
Now, if the launch angle of the rocket is simply the angle of attack, and the momentum of the rocket is not changed, then the change in kinetic energy increases as the rocket moves upwards. If the launch angle is a bit steeper, the change in kinetic energy increases linearly with increasing altitude. In this case, we find that the gravitational potential energy decreases with increasing altitude. Thus, it is possible to increase the height of objects by converting gravitational potential energy to kinetic energy. This process can be used to raise platforms or towers by using the concept ofraction. The bottom part of the tower or platform has more weight than the top part, so by adding the kinetic energy increases, and the bottom part of the platform or tower is raised to account for the difference in gravitational potential energy.
When an object that has gravitational potential energy moves in the opposite direction to its momentum, then it will have less potential energy. This means that the object loses its momentum. This can be used in engineering applications, such as in the aerospace industry. A rocket stage may separate from the rocket while in flight, and this separates the vehicle from its potential energy and the stored momentum and requires some way to restore the lost energy to the stage.
