What actually are Newton's axioms of classical mechanics

In summary, there are three different formulations of classical mechanics: the Euler-Lagrange differential equation, the Hamiltonian equations, and the Poisson equation. These are all considered axioms, and the Newtonian formulation of classical mechanics can be explicitly formulated using "standard" mathematical language. However, it should be noted that Newton did not work axiomatically and instead used Euclid's axioms for geometry to describe observations and experimental results in his work.

Just like the Euler-Lagrange differential equation
$$ \frac{\partial{\mathcal{L}}}{\partial{q}} = \frac{d}{dt}\frac{\partial{\mathcal{L}}}{\partial{\dot{q}}} $$
the hamiltonian equations
$$ \frac{\partial{H}} {\partial{q}} = -\dot{p} $$
$$ \frac{\partial{H}} {\partial{p}} = \dot{q} $$
and the poisson equation
$$ \left\{F,H\right\} = \dot{F} $$
are axioms to different formulations of classical mechanics. What are the axioms of the Newtonian formulation?

Are his three laws separate statements that together make up the axiom? Or are the laws the actual axioms? In which case, can the Newtonian formulation of classical mechanics be explicitly formulated in "standard" mathematical language?

EDIT: by non-"standard" I mean like the fact that ## F_{12}=-F_{21} ## makes no sense if not followed by subtitles. And that it only makes sense in a very specific context..

I don't think Newton worked axiomatically - in Principia he used Euclids axioms for geometry implicitly, and used that framework to describe/record observations and the results of experiments.

What are Newton's axioms of classical mechanics?

Newton's axioms of classical mechanics are a set of three fundamental principles that govern the motion of objects in the physical world. They were developed by Sir Isaac Newton in the late 17th century and are considered the foundation of classical mechanics.

What is the first axiom of Newton's classical mechanics?

The first axiom, also known as the law of inertia, states that an object at rest will remain at rest and an object in motion will continue in a straight line at a constant speed unless acted upon by an external force.

What is the second axiom of Newton's classical mechanics?

The second axiom, also known as the law of acceleration, states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is expressed mathematically as F = ma, where F is force, m is mass, and a is acceleration.

What is the third axiom of Newton's classical mechanics?

The third axiom, also known as the law of action and reaction, states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object will exert an equal but opposite force on the first object.

Why are Newton's axioms important?

Newton's axioms are important because they provide a framework for understanding and predicting the behavior of objects in the physical world. They have been tested and proven to be accurate in countless experiments and form the basis for many other laws and principles in physics.
