How to caculate Thrust?

  1. Mar 14, 2004 #1
    I'm buildind a hover craft for a Physics project. I have built it, and am need ing to calculate how much thrust my leaf blower has to put out in order to lift me up, how do i do that? Same thing with forward movement, how do i figure out how much thrust it will take to move me forward if i'm basically hovering off the ground? Thanks!

    To lift you, the thrust needs to be larger than the mass of the vehicle times the acceleration of gravity.

    For sideways motion, the needed thrust depends on your desired acceleration.
