I read over that other thread. I couldn't quite understand though. Did you ever find equations for the acceleration of gravity with respect to time, or did you just approximate the values?
My friends and I have a problem that seems simple enough, but has proven to be pretty hard. We need some help.
Suppose you have an object in space with no initial velocity relative to the Earth.
Now, due to the Earth's gravity, the object will begin to accelerate towards the Earth...
