Different rocket launchers and flight profiles inherently produce varying acceleration and G-force profiles for their payloads, making this a matter of basic aerospace engineering and physics that requires no formal citation.
The claim is a straightforward physical and engineering fact based on everyday observation and foundational aerospace principles (different rockets have different thrust profiles, masses, and staging designs, resulting in varying G-forces). None of the retrieved papers directly study a comparative set of multiple different rocket launchers and their payload G-forces as a central thesis, though the topic is common knowledge. Therefore, the verdict is COMMON_KNOWLEDGE with no citations needed.
