What is a g-force and whats the equation for calculating a g force?

Question

I need help please

Answer 1

G-force is how much force is put on a human body by the force of gravity.

G-forces are calculated by figuring out how much acceleration is put on a body (whether rotating, stopping, or starting), and dividing that by one G, which is 9.8 m/s^2

Answer 2

It's been a LONG time since I had to do any of this stuff. Most physics basic physics equations can be deduced from the basic F=ma. Gravitational force is mass of the object times the accelleration of gravity (9.8m/s). Now somewhere in there, I believe that you need to either multiply by the number of g's that you are looking for (i.e. calculating 3 g's of force), or divide by 9.8m/s if you are given one big fat force amount and are told to figure out the g's from that. Since I don't know your actual unknowns, then I am really not entirely sure.

Answer 3

G force is the equivalent of your weight on the earth's surface. It's the force that would cause you to accelerate at 9.8 m/s^2.

So if your plane is turning with a centripetal acceleration (v^2 / r) of 30 m/s^2, that's three times the acceleration due to gravity (just under 10 m/s^2), so you say you are pulling three g's.

Answer 4

Use conservation of power. The power initially saved interior the object (skill power) = power dissipated for the period of result. hint, the shape of the two facets of the equation is the comparable different than the distances and accelerations are diverse (mass is the comparable, of direction). giving you any further could no longer likely help you. assume result forces to be a hundred's or perhaps one thousand's of G's.

Answer 5

A "g" force is simply a force that is experienced from acceleration, be it gravity or changing velocity.

The equation for calculating the force is:

force = mass * acceleration
