How to calculate average force from impulse

Web3 feb. 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. WebImpulse is the area under the curve of the force vs. time graph. Areas above the time axis are positive \Delta p Δp and areas below the axis are negative \Delta p Δp. If the force is …
