Question

How are momentum and impulse calculated?

Answer 1

`rho=summv`

`∫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.
