Hey everyone!
I've done http://www.fourmilab.ch/gravitation/foobar/" and i find it interesting how objects of any mass just randomly attract each other. Anyway, i always wanted to find out how long it should take for a mass in this experiment to gravitate towards the other. The problem is it isn't like doing it on Earth where at the surface everything accelerates at 9.8m/s. The only relevant equation for acceleration in this case would be
G*M/r^2
G=6.67*10^-8cm³/g-sec²
m=mass in grams
r=distance in cm
I just learned a LITTLE calculus but so far i can only calculate how long it will take for an dropped object to hit the ground. I was hoping i could use this but since the acceleration is always changing i don't know how to do this out. Can someone help??
Thanks
