What is the fundamental principle of dynamics ?

The Newton's second law of motion is part of the three laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it. The second law states :

A body acted upon by a force moves in such a manner that the time rate of change of momentum equals the force.

Mathematically, this relationship is summarized by each of these equations:







Where:

•  are the external forces applied to the object
•  is the mass of the object
•  is the acceleration of the object
•   is the velocity of the object
