Discussion Overview

The discussion revolves around calculating the period during a rocket launch that produces a certain g-force. Participants explore the relationship between acceleration, velocity, and g-force, seeking to clarify the relevant formulas and concepts involved in this context.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant inquires about the formula for calculating the period of rocket launch that results in a specific g-force.
  • Another participant notes that one g of acceleration is approximately 9.8 meters per second squared, indicating that at that acceleration, the craft experiences one g in addition to gravitational acceleration.
  • A different participant challenges a previous claim regarding the relationship between g-force and velocity, asserting that g-force is dependent on acceleration rather than velocity, and proposes a formula for calculating g-force based on acceleration.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between g-force, acceleration, and velocity, indicating that there is no consensus on the correct formula or understanding of the concepts involved.

Contextual Notes

There are unresolved aspects regarding the definitions and assumptions related to g-force and its calculation, as well as the specific context of the rocket launch being discussed.

How do you calculate the period during rocket launch that produces a certain g-force? Is there a formula to work this out?

My apologies HallsofIvy. I've been experiencing ISP issues and getting bumped repeatedly, so I typed up what I thought may have been the "quick and easy" explanation, posted it, and didn't have a chance to thoroughly recheck it before I got bumped again. It took me the last 20 minutes or so just to get reconnected.

It will depend on each specific situation. One g of acceleration is about 9.8 meters per second per second. 9.8m/s^2

So at the point in the launch the rockets speed is changing by 9.8m/s^2 the craft is experiencing one g over and above the acceleration due to gravity.
 


? G force has nothing to do with velocity- it depends on acceleration. Was that just a repeated misprint? (Referring to Gnosis' post.) The formula should be (a/g)+ 1, not (v/g)+ 1. That is, you feel your normal weight due to gravity plus an additional "weight" due to the force causing the acceleration.
