   In classical mechanics, impulse (symbolized by J or Imp) is the change in momentum of an object. If the initial momentum of an object is p1, and a subsequent momentum is p2, the object has received an impulse J : Momentum is a vector quantity, so impulse is also a vector quantity. Newton’s second law of motion states that the rate of change ...

   Momentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p . By definition, p = m ⋅ v. Where m is the mass and v is the velocity. The standard units for momentum are kg ⋅ m / s , and momentum is always a vector quantity.
