**Joules to G Force Calculator**

Enter the values of energy in joules, J_{(J)}, mass of the object, m_{(kg)} and distance over which the energy is applied, d_{(m)} to determine the value of G-force, GF.

**Joules to G Force Formula**

The conversion from joules (a measure of energy) to G-force (a measure of acceleration relative to Earth’s gravity) involves calculating how much force in terms of gravitational force units (Gs) is associated with the release or absorption of energy over a certain distance, taking into account the mass of the object involved.

G-force, GF in g-forces is calculated by dividing the potential energy in joules, J_{(J)} in joules by the mass of the object, m_{(kg)} in kilograms, the distance over which the energy is applied, d_{(m)} in metres and then normalizing by the acceleration due to gravity, 9.81m/s^{2}.

G-force, GF = J_{(J)} * m_{(kg)} / d_{(m)} * 9.81

GF = G force in g-forces.

J_{(J)} = energy in joules, J.

m_{(kg)} = mass in kilograms, kg.

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

__Joules to G Force Calculation: __

**Calculate the G-force exerted when a device with 150 joules of kinetic energy and a mass of 30 kg comes to a stop over a distance of 0.25 metres.**

**Given: **J_{(J)} = 150J, m_{(kg)} = 30kg, d_{(m)} = 0.25m.

G-force, GF = J_{(J)} * m_{(kg)} / d_{(m)} * 9.81

GF = 150 * 30 / 0.25 * 9.81

GF = 1835.49Gs.

**Suppose a device uses 500 joules of energy to achieve a G-force (GF) of 100 Gs over a distance of 2 metres. Calculate the mass of the device.**

**Given: **J_{(J)} = 500J, GF = 100Gs, d_{(m)} = 2m.

G-force, GF = J_{(J)} * m_{(kg)} / d_{(m)} * 9.81

m_{(kg)} = GF * d_{(m)} * 9.81 / J_{(J)}

m_{(kg)} = 100 * 2 / 9.81 * 500

m_{(kg)} = 3.924kg.
