__Impact G Force Formula:__

The impact G-force formula is used to calculate the force experienced by an object upon impact, translating its kinetic energy at the moment before impact into a force experienced over the distance through which it decelerates.

Impact G-Force, IGF_{(Gs)}, is calculated as the deceleration divided by the standard acceleration due to gravity (9.81 m/s²), where the deceleration is derived from the change in velocity squared, v_{(m/s)} in metre per second is divided by twice the distance over which the deceleration occurs, d_{(m)} in metres.

Impact G-Force, IGF_{(Gs)} = v^{2}_{(m/s)} / 2 * d_{(m)} * 9.81

IGF_{(Gs)} = impact G-Force in Gs.

v^{2}_{(m/s)} = velocity before impact in metre per second, m/s.

d_{(m)} = deceleration distance in metres, m.

__Impact G Force Calculation:__

- An object falls and impacts the ground with a velocity of 10 m/s, compressing a cushioning material to a depth of 0.25 metres upon impact. Determine the impact G-force absorbed by the cushion.

Given: v^{2}_{(m/s)} = 10m/s, d_{(m)} = 0.25m.

Impact G-Force, IGF_{(Gs)} = v^{2}_{(m/s)} / 2 * d_{(m)} * 9.81

IGF_{(Gs)} = 10^{2} / 2 * 0.25 * 9.81

IGF_{(Gs)} = 20.39Gs.

- Suppose an object impacts a surface at a speed of 15 m/s, and the impact G-force experienced is 30 Gs. Find the distance over which the object decelerates.

Given: v^{2}_{(m/s)} = 15m/s, IGF_{(Gs)} = 30Gs.

Impact G-Force, IGF_{(Gs)} = v^{2}_{(m/s)} / 2 * d_{(m)} * 9.81

d_{(m)} = v^{2}_{(m/s)} / 2 * IGF_{(Gs)} * 9.81

d_{(m)} = 15^{2} / 2 * 30 * 9.81

d_{(m)} = 0.382m.
