Solve Science Fair Experiment: Calculating G-Forces

[hsstudent]

First, I would like to say that I am doing a science fair experiment testing the effectiveness of different polymers in absorbing hits. I have decided that I am looking to exert about 25 g-forces on each polymer. Average football hits are in the 50 g- force range, and taking everything into account, I think half of that is reasonable. If you think that is too much, please let me know, but I am hesitant to go any higher than that. What I am asking is, I haven't really seen any definitive answers on how many Newtons are in a g- force, or how many pounds of force are in a g- force. So I am essentially looking for a mass and acceleration to do my experiment with

F=ma

The Attempt at a Solution

F=ma
F=m(9.8 m/s^2)
F/m=(9.8m/s^2)

You ought to use a more accepted measure of force such as Newtons (most widely accepted) or lb-force (most widely known as the lb).
