"WebFeb 3, 2024 · Impulse is defined in classical mechanics as a force multiplied by the amount of time it acts over. In calculus terms, the impulse can be calculated as the integral of force with respect to time. The symbol for impulse is J or Imp. Force is a vector quantity (the direction matters) and impulse is also a vector in the same direction. " - Change in time definition physics
