last question from me of the PS section.

Which is equal to change in momentum of an object?

A. Force
B. Acceleration
C. Velocity
*D. Impulse

So what's up.

FORCE

let p = momentum

Force = kg * m/s² = (kg*m/s) / s = p / t
Force = p / t

change in momentum of an object over time

IMPULSE

p = F*t
F = p / t

😡😡

You've written out all the right work, so where are you confused?

F = ma = m*&#916;v/t = &#916;p/t

J = Ft = (&#916;p/t)(t) = &#916;p

Force = rate of change in momentum
Impulse = change in momentum

daaamn

it's true 🙁

make it simple Impulse=change in momentum
