The discovery of the laws of dynamics was a decisive moment in the history of Physics. Before the works of Newton, the movement of objects was a mystery, and nobody could explain why things move as they do. Since ancient times astronomical tables had been drawn up to record the movement of celestial bodies, but no theory had been found to explain it.
The Newton’s law of motion (1687) are the pillars of Classical Mechanics. They describe the translational motion that a body has due to the interactions (forces) it experiences with the objects that surround it.

Since Newton’s laws of motion describe only the translational motion, they do not depend on their shape or volume. Therefore we will speak indistinctly of body or particle.
On this page we will focus on its meaning and application of Newton’s laws. You can find a more detailed deduction of these laws here.
Newton’s laws of motion are valid when applied in an inertial reference frame:
An inertial reference frame is one that has no acceleration and is not rotating.
