Capacity of a body when producing work
In a general use it is said that energy is the force or power that something or someone has, meanwhile, in the field of physics, which is where the concept that will occupy us next is used, energy is the capacity that it presents a body when producing, generating work. In the case of kinetic energy, one of the many types of energies with which we can come across, it is the energy that any body has due to its movement, that is, the one that originates from moving.
That which will possess any body as a consequence of its movement
It is known as Kinetic Energy to that which any body will possess as a consequence of its movement and for case it will depend on the mass and speed that it presents.. So, it is the energy that is closely related to the bodies that are in motion.
Windmills are moved by kinetic energy
If we had to mention an example to understand it clearly, we will cite the one of the wind moving the blades that make up a windmill.
This energy has been studied and is vital for the development of many activities for several centuries. The windmills whose main mission is to grind wheat make use precisely of this energy and are fundamental elements at the request of this task.
It is often referred to in writing as Ec or Ek.
How does this energy work?
Kinetic energy is the essential task to precipitate a certain body of a mass from what is understood as its rest to the speed it reaches, then, once the activation is achieved, any body will maintain its kinetic energy as long as it does not modify its speed. Meanwhile, for the body to return to a state of rest, work is essential, but the reverse of the body, in the negative sense of kinetic energy..
As with other physical magnitudes that are functions of speed, kinetic energy will not only depend on the object itself, on the internal nature that it manifests, but will also depend on the relationship established between the object and the observer, than in physics, not to believe that it is a person as in other areas in which this word is used, but that here it is embodied by a precise coordinate system.
Calculation of kinetic energy
To carry out the calculation of kinetic energy there are different ways and they will depend on the type of mechanics used, be it classical, quantum, relativistic and also factors such as size, the speed of the body will have an impact on the calculation. and the particles through which it is formed.
An example that will help us to better understand this question of kinetic energy and how it is transformed into other types of energy and other types of it ... the cars that make up a roller coaster achieve the maximum of their energy when they are towards the end of the When traveling, at the moment of having to rise, the kinetic energy will immediately be transformed into gravitational energy, the energy remaining constant, even at the expense of friction or other factors that imply delay.
Kinetic energy classes
There are different types of kinetic energy, that of translation, which occurs when the components of an object continue in the same direction. For its part, the kinetic energy of rotation is that which occurs when the parts of the object rotate.
And molecular kinetic energy is that which is possible to observe in molecules of matter.
The British physicist and mathematician William Thomson, or First Baron Kelvin, after having received the distinction for having been the creator of the Kelvin temperature scale, is one of the most important contributors to the matter of kinetic energy.
