Delta Vee

  1. Mar 9, 2012 #1
    I am doing an assignment about launching a rocket and at the moment im looking for the delta V of the rocket. I have done a few researches and i found a method of finding the energy of the rocket and find the delta vee of it , but then i found this article and im not sure if it is delta vee or not, and i dont get why there is a 1km/s in the equation

    welcome to pf!

    hi marco12345a! welcome to pf! :smile:

    ∆v is the increase in speed while the main rocket burns

    1 km/s must be the speed just before the main rocket starts to burn

    (but i don't know where that comes from … it's over twice the earth's rotation speed :confused:)
