When a body is in motion we say that it produces or contains Kinetic Energy, in other words it is the energy associated with objects that are in motion. The term "Kinetics" is of Greek origin and was derived from the word "kinesis" whose meaning is movement. To use force or work on an object that is in a state of rest, enough to cause its acceleration and make it move..
Having achieved this acceleration is what is known as kinetic energy, it will not change unless the speed of the moving object changes, if an external force is exposed on the body, its direction and speed can vary and consequently also its kinetic energy. To get said object to stop (to return to its state of rest) it is necessary to apply an opposite or negative force that must be equal to the amount or magnitude of kinetic energy that it possesses at that moment.
It is very important to take into account that all matter has internal energy, however in order to give kinetic energy to an object, you must work or use force (which is the possibility that a body has to affect another) on it so that it can be done. put in motion. Taking into account that energy is not created or destroyed, it is transformed, it is possible that through kinetic energy other types of energy are produced (due to movement), such as wind energy.
