System Output. The assumption of a constant force in the definition of impulse is analogous to the assumption of a constant acceleration in kinematics. The impact time between the floor and the egg is short, which means that the force (which is impulse divided by time) becomes large enough to crack the egg. The bed sheet increased the collision time and as a result, the force of impact was reduced. Impulse J produced from time t 1 to t 2 is defined to be = where F is the resultant force applied from t 1 to t 2.. From Newton's second law, force is related to momentum p by = Therefore, = = = = where Δp is the change in linear momentum from time t 1 to t 2.This is often called the impulse-momentum theorem (analogous to the work-energy theorem).. As a result, an impulse may also be regarded . By rearranging the equation [latex]{\mathbf{F}}_{\text{net}}=\frac{\Delta\mathbf{p}}{\Delta t}\\[/latex], to be Δp = FnetΔt, we can see how the change in momentum equals the average net external force multiplied by the time this force acts.
