WebThe 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 of momentum. WebWhen we’re dealing with variable mass, we have this extra term of 𝐯d𝑚 by d𝑡.
