I have reasons to beleve that this formula did'nt belong tgo newtonian physics in the beginning. Couls anywone tell me who invented it, and when, how and by whom it was incorporated in mathematical physics during the XVIII century?

I suggest you enter "Marquise du Châtelet" in Google. Clic on the 4th item:"Marquise du Châtelet"(elle traduisit Newton. Thank you for tzelling me wether this extract helped you answer my question about 1/2mv2.
Thanks

This was part of Newtonian Physics from the beginning. Isaac Newton derived this equation using his Laws of Motion, the definition of momentum (which he thought of), and the new mathematical method he developed, Calculus.

The etymology of 'kinetic energy' is the Greek word for motion kinesis and the Greek word for active work energeia. Therefore the term 'kinetic energy' means through motion do active work. The terms kinetic energy and work and their present scientific meanings date back to the mid 19th century. Early understandings of these ideas can be attributed to Gaspard-Gustave Coriolis who in 1829 published the paper titled Du Calcul de l'effet des machines outlining the mathematics of kinetic energy.

Newton certainly knew about it. Whether it was developed before Newton, I don't know. The formula can be derived from a mass starting from rest, undergoing constant acceleration:
W
= Fd
= (ma) d
= md (v_f-v_0)/t
= m t(v_f+v_0)/2 (v_f-v_0)/t
= m (v_f+v_0)(v_f-v_0)/2
= m (v_f)(v_f)/2
= mv^2/2
