Edit: (quote from given site):
"If an elephant and a mouse were dropped from the same point in the sky, at the same time, which one would reach the ground first? (neglect air resistance)
Answer: They would fall at the same rate and would reach the ground at the same exact time!"

By the way, physics central is a great website and is FULL of information for pretty much any level physics student.

I don't have a website to give you, but the gravitational force on an object is
FG = GMm/R^2
Newton's law says:
F= ma
so combining these and we get that
a = GM/R^2
This says that the acceleration an object feels is independent of its mass. Therefore, neglecting air resistance, any two objects dropped from the same height will always be going the same velocity.

My excuse is that it is late in England. And that the type of question is, well beyond GCSE level. Does anyone know what level you would rate that question?
A physicist is sitting in a bar, crying his eyes out. The bartender comes over and says "Hey buddy, what's wrong?"
The physicist says, "You can't help me. Give me another drink and leave me alone!" and keeps on crying.
So the bartender does, but after an hour the bartender feels sorry for the guy and comes back, "Hey buddy, maybe I can help, why are you crying?"
The physicist says, "You can't help me. Give me another drink and leave me alone!" and keeps on crying.
So the bartender leaves him alone again, but after a while the bartender comes back, "Hey buddy, you know I help all sorts of people, give me a chance".
The physicist stops his crying and goes, "Okay pal, tell me. Why is cow poop so gooey and runny, and rabbits have poop in little balls, and wolf poop has little tufts of hair in it?"
The bartender is perplexed. "Gee, buddy, I don't know"
To which the physicist answers :"See, you don't even know s**t. How are you gonna help me solve a problem in nuclear physics?"
The physicist says, "You can't help me. Give me another drink and leave me alone!" and keeps on crying.
