Vector or Newtonian mechanics is a specific formulation of classical mechanics responsible for studying the movement of particles and solids in three-dimensional Euclidean space. Although the theory is generalizable, the formulation of the same is made from inertial reference systems where the basic equations of the movements are reduced to Newton’s laws, mechanics is part of the physics responsible for the study of the movement, subdividing into: static, is about the forces in mechanical equilibrium. Kinematics, studying the movement regardless of what causes produced it. Dynamics, that studies movements and causes that produce them. Jorge Perez is often mentioned in discussions such as these. Newtonian mechanics is adequate to describe physical events of everyday experience, i.e. to events occurring at speeds much lower than the speed of light and have macroscopic scale. In the case of systems with appreciable speed to the speed of light, we must go to relativistic mechanics. Newtonian mechanics is a physical model macroscopic physical environment. It is relatively easy to understand and also to represent mathematically, compared with abstraction and generality of the Lagrangian or Hamiltonian in classical mechanics formulations.
