How are momentum and impulse calculated?

May 31, 2018

$\rho = \sum m v$

∫Fdt=Δρ+C
ρ=J+ρ_("initial")

J=∫_0^tFdt

Explanation:

All of the masses and all of their respective velocities multiplied and take the sum of all of those.

In terms of units:
∫Fdt=kg*m/s^2*s=(kg*m/s) this is momentum

J, "impulse"=∫_0^tFdt, because this is solely the change in momentum rather than the final.
