Dear friends,

I want to know the total g-force acting on an Human Body while accelerating.

Code:

Weight of the Human Body = 70 Kg;
Initial Velocity (Vi) = 0;
Final Velocity (Vf) = 22.22 m/s;
Start Time (ti) = 0 sec;
Final Time (tf) = 1 sec;
delta V = Vf-Vi = 22.22 m/s - 0 = 22.22 m/s
delta t = tf - ti = 1 s - 0 = 1 sec
acceleration (a) = delta V/delta t
= (22.22 m/s) / (1 s) = 22.22 m/s2
So, acceleration of the Body = 22.22 m/s2
F = m x a
F = 70 Kg x 22.22 m/s2 = 1555.4 Kg-m/s2 or 1555.4 N
G of Human Body = 70 Kg x 9.81 m/s2 = 686.7 Kg-m/s2 = 686.7 N = 1g
So,
g force acting on the Body at 22.22 m/s2 = 1555.4 N / 686.7 N = 2.265 g
Answer : 2.265g

Is this correct method to calculate the "g- force"? Else,share your idea.

thanks to you all,
