Dynamics is a branch of physics that studies and describes the evolution over time of any physical system, especially, it focuses its interest on those factors capable of causing alterations in the physical system, object of study and for this it will quantify them and propose equations of movement and evolution in relation to the aforementioned system.
Mechanical, classical, relativistic or quantum systems are those in which dynamics focuses its work.
Isaac Newton was the first scholar to formulate some fundamental laws in this field of study, which, later, would become a body of theories that offer the correct answers for most of the problems related to bodies in motion or those that arise while they are being studied.
The laws of dynamics have a particular importance for man in general, whether or not he is a student of the subject, because the understanding of them is what will allow the common man to determine issues such as the value, meaning and direction of the force that must be applied in order for the body to produce a certain movement or change. For example, for a balanced and safe cargo transport to travel, it will be necessary to apply force to it in the most appropriate place and this can be done by virtue of the dynamics of course.
