How does momentum relate to impulse ?
fomenos

Answer:

C. Impulse = F*t=(m*a)*t= m*(a*t) = m*Dv= D(Momentum) (“D” here’s mean Delta so change in)

Explanation:

In fact, the impulse is equal to the change in momentum of an object.

Impulse is defined as the product between the force (F) and the time (t):

I=Ft

however, the force is defined as the product between mass (m) and acceleration (a):

F=ma\\I=(ma)t

But the product a (acceleration) times t (time) is equal to the change in velocity of the object:

I=m(at)=m \Delta v

And this is exactly the definition of change in momentum:

I = m\Delta v = \Delta p
