Homework Statement
How does change the total energy of the rocket during its motion inin a uniform gravitational field?
2. The attempt at a solution
My idea is to write the law of conservation of energy systems - "rocket- gases" ##\frac{dE_{total}}{dt}=0##
But get very cumbersome terms , the physical sense , I can not understand.
Besides, it is not clear how to express the change of potential energy of emitted gases .
