[32] Steinfeldt B. The Tsiolkovsky rocket equation, classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity can thereby move due to the conservation. Show more Show less. I'm trying to model projectile motion with air resistance. Prototypes will break. As a rocket scientist, you have been given a task to perform a trade study to select between three different launch trajectories. The initial and final velocity must be zero and the maximum velocity can never exceed 1. A rocket trajectory is adjusted by varying the thrust over the course of a launch. The following files demonstrate one way to calculate and graph various quantities related to classical projectile motion.
