Multi-stage rockets require more force to keep the rocket moving.

The statement "Multi-stage rockets require more force to keep the rocket moving." is false because the multi-stage rockets do not require rocket to move.

Explanation:

A multistage rocket or step rocket is a launch vehicle that uses two or more rocket stages, each of which carries its own engines and explosive. A tandem or serial stage is positioned on top of another stage; a parallel stage is indicated adjacent to another stage.
