Dear ocean,

Consider a generic interaction between 2 objects, as shown to the right. A mass m1 moving with a speed v1 interacts with a mass m2 moving with a speed v2.

Leibniz was a contemporary of Newton. He noticed that for many types of interactions the sum of the quantity mv2 was the same value before and after the interaction:

He called this quantity the vis viva, or "living force," and for him its conservation was central to his thinking about interactions.
