P1199560 Impulse and momentum / demonstration track with Cobra4 Principle An impulse is described as the change in momentum by a force applied upon a body for a small interval of time. The momentum is defined here as the product of force and time and is conserved if no friction loss occurs. This means that in a closed system of different bodies the latter can transfer or receive momentum, however the total momentum of the system remains temporally and quantitatively constant.
