It is F*t = m*dV or F*t = m*v - m*u
where:
F is the force, acting for time t,
m is the mass of the object, dV it the change in its velocity
u and v are the velocities of the object before and after the impulse.
There are several equations that relate to impulse or momentum. Here are two:Delta momentum = 0 (that is, the momentum doesn't change over time)
Impulse = force x time (definition of impulse)
or more generally:
Impulse = integral F dT
Impulse = Force x time
Momentum = mass x velocity
Ft = mv
Impulse=Force*time=change of momentum
impulse generator equation is a difference of two exponential functions V0 = Vs/k (exp-at - exp-bt)
Impulse-momentum theorem
change in momentum
An impulse is a change in momentum.
Impulse = [(change in momentum)/time]*time[(change in momentum)/time] = ForceAnd when force acts for a period of time, that impulse changes the momentum of the object.You can also rewrite the impulse equation as: I = F*tHowever, for change in momentum times time, the units would be (kg*m/s)*(s) = kg*m. These units are not in common usage.

Impulse-momentum theorem
impulse = change in momentum so, no
Impulse-momentum theorem
Impulse is integral of linear momentum with respect to time, and in limits when that momentum was transferred.
