    Undergrad Acceleration increasing with altitude under constant thrust

    All true, anorlunda, A.T., and Nugatory, and thank you for the discussion of the force of gravity and gravitational acceleration, but still not the answers I need. I am holding T constant, which will cause my resultant acceleration to grow over time. With that in mind, what are my equations...

    Undergrad Acceleration increasing with altitude under constant thrust

    Gravity is a force, anorlunda, and 1.05 times gravity is also a force.

    Undergrad Acceleration increasing with altitude under constant thrust

    jbriggs, exactly. I'm trying to determine the Earth-relative speed (thank you for getting my terms straightened out) of a mass as it rises at 1.05G proper acceleration. I've got the formula for my Earth-relative acceleration [1.05G - GravConst*EarthMass*MassObject/(distance from center of...

    Undergrad Acceleration increasing with altitude under constant thrust

    I assure you that if you read the entire premise, the "instantaneous acceleration" at the start isn't static. The force given is 1.05G at lift, but due to the force of gravity of the earth, at sea level, the actual force upward is 0.05G. However, as the craft rises in altitude, the force from...

    Undergrad Acceleration increasing with altitude under constant thrust

    I've seen much about jerk, and how it's generally nearly instantaneous, and for general acceleration, that's fine. However, if I lift at a constant acceleration upward slightly stronger than gravity is pulling me downward, the gravitation pull of the Earth will offset part of my force, so that...

    Writing Accurate SciFi: Balancing Imagination and Scientific Validity

    Hey, folks. I'm a college grad, but that was many years ago (1984, and yes, I still feel like the novel "1984" is discussing a year in the "future"). I'm now working in the tech industry, but am trying to write SciFi. Unlike some SciFi, though, I want it to be relatively accurate. Oh, sure...
