  In 1721, John Jennings published Miscellanea, where the momentum in its current mathematical sense is attested, five years before the final edition of Newton's Principia Mathematica. Momentum M or "quantity of motion" was being defined for students as "a rectangle", the product of Q and V, where Q is "quantity of material" and V is "velocity", s / t.
  
  In 1728, the Cyclopedia states:
  
  The Momentum, Impetus, or Quantity of Motion of any Body, is the Factum of its Velocity, (or the Space it moves in a given Time, see Motion) multiplied into its Mass.
