    සංස්ථිතික නියමවල ප්‍රයෝජනය පවතින්නේ යම් කාල පරාසයක් පුරා ඒවායේ යෙදීම තුළය. ඔබ එය ගැටුමක් සඳහා යොදන්නේ නම්, එසේ යොදනුයේ ගැටීමට මොහොතකට පෙර සහ ගැටුමට මොහොතකට පසු ප්‍රවේග පිළිබඳ තොරතුරු ලබා ගැනීම සඳහා ය.

    එබැවින්, එම තොරතුරු ලබා ගැනීමට වඩාත් සුදුසු ක්‍රමය නම් ගම්‍යතාවයේ හදිසි වෙනස්වීම් පාලනය කරන සමීකරණය වන I=Δ(mv) යෙදීමයි.

     

    The usefulness of conservation laws lies in their application over a period of time. If you are applying it for a collision, you will be applying it to get information on the velocities just before and just after the moment of impact.

    Therefore, the more appropriate way to get that information is to apply I=Δ(mv) since it is the equation governing the sudden change in momentum.
