Momentum is mass * constant velocity, impulse involves imposing a force (either for or against) for a specified time , altering the velocity (and therefore, momentum)
>
Example. a 10 kg mass (m) @ 10 metres / second, has an impulse of 100 newtons / 10 seconds (t) applied in the direction of motion.
Find the velocity change / new velocity / initial and final momentum
>
From f = m * a, but a = velocity change (vc) / time (t)
So>
f = m * (vc / t)
Then>
vc = t * (f / m) = 10 * 10 = 100 metres / sec velocity change (+ in this case)
so, velocity is now 10 + 100 = 110 metres / sec (constant velocity)
>
initial momentum (p) = 10 * 10 = 100
momentum (after impulse) (p) = 10 * 110 = 1100
>
Alternatively, to calculate final velocity after impulse
First, find acceleration rate from a = f / m
you know the impulse time, you know the initial velocity.
>
Use v = u + (a*t)
v = 10 + (10 * 10)
v = 110 metres per second
F= m(v-u)/t or Ft= mv-mu... Impulse. Impulse= change in momentum. The unit of impulse is the newton second (Ns). Since this quantity is equal to change in momentum it means that momentum can also be expressed in Ns. Impulse=Ft=change in momentum.
A force is required to change momentum.An "impulse" refers to the amount of momentum transferred; impulse can be defined as force x time (more precisely: the corresponding integral).
Impulse is a change of momentum (delta p).
Force = mass x acceleration = kg(m/s^2) or N Momentum = mass x change in velocity = kg(m/s) or Ns The units of impulse are the same as momentum's because impulse is just the change in momentum.
The impulse or the 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.
An impulse is a change in momentum.
Impulse is integral of linear momentum with respect to time, and in limits when that momentum was transferred.
