Detailed explanation-1: -The total weight of the rocket is reduce as the rocket rises. Multistage rocket has a bunch of thrust. The main advantage is that it drops useless weight and goes faster.
Detailed explanation-2: -Optimizing the structure of each stage decreases the weight of the total vehicle and provides further advantage. The advantage of staging comes at the cost of the lower stages lifting engines which are not yet being used, as well as making the entire rocket more complex and harder to build than a single stage.
Detailed explanation-3: -The total weight of a multistage rocket is greatly reduced as the rocket lands. False–The total weight of a multistage rocket is greatly reduced as the rocket RISES.
Detailed explanation-4: -Because the amount of fuel it takes to launch a rocket is so high, modern rockets use a staging system. Once a stage has emptied out all its fuel, it detaches and returns to Earth so that the second stage can keep going without having to drag along the extra weight of the empty fuel tanks.
