How does Gravity work in the BGE?

I was testing gravity out in the BGE and it appears after a couple of tests that it doesn’t actually fall at a rate of 9.807 m/s**2 but rather at varying rates.

#x starting at zeroe.
#x as tics.
#y as Z position from start.

i also recorded the Z position from start of a falling object and got this which when graphed looks a little like:

i tried to find a formula to match it and as close as i got was:
y=-0.001252x^{2}
which is still inaccurate so please if you know, do tell me how the BGE calculates gravity or if its any different from other havoc sims.

Alongside gravity, the Bullet Engine also takes into account:

  • World Physics Deactivation

  • And individual Object physics such as Mass, Linear & Angular Velocity, Damping, and many more physic factors

yes but i was hoping for an in depth explanation as to how it derives its conclusions FROM that data.

damping makes a mess of the physics, be sure linear damping is at zero
