A BRIEF DEFINITION OF FORCE VIVE and SQUARING 


Force Vive (F;mv2) is a scientific concept that was hotly debated in the 17th and 18th centuries. Proposed by Gottfried Leibniz over the period 1676-1689, the theory was controversial as it seemed to oppose the theory (F;mv) advocated by Sir Isaac Newton. In Leibniz's view, New­ton's equation of was incorrect because it eventually becomes zero, meaning that the force stops and is "dead." Newton explained that God would add more energy to keep the universe going. Leibniz's squar­ing of velocity meant that force keeps going and doesn't need outside replenishment of energy (i.e. it was "alive"). During the French debates on the subject, Newton's equation became known as "Force Morte," (Dead Force) while Leibniz's equation was called "Force Vive" (Living Force). However, Leibniz's theory was not clearly explicated and lacked a detailed experimental proof, and Newton proved too powerful of an intellectual celebrity to overcome. 

 

By advocating for Leibniz's squaring of Force, Emilie Du Chatelet trans­lated Leibniz's idea in a way that was easily understood and added the decisive evidence on squaring of a Dutch researcher, William 'sGraves­ande. Today, due in part to Du Chatelet's work, we understand that the two equations are describing different things - Newton's equation describes the Conservation of Momentum (F;ma - Force equal Mass times Acceleration), while Leibniz's equation became what is under­stood as Kinetic Energy (E;mv2) - Energy equals Mass times Velocity squared). 

 

Scholars see Du Chatelet's legacy as including her advocacy of squaring and her French translation of Newton's Principia. These and her other writings prompted scientists of the following centuries to regard energy as being proportional to mv2, and she can be traced to Einstein's devel­opment of E;mc2.Thank you to Dr. Judith Zinsser, whose mentorship and book, Emilie Du Chatelet: Daring Genius of the Enlightenment (Penguin, 2007), gave me so much of the world of this play. -- Lauren Gunderson
