Basically, this means that, in theoretical terms, if we remove all gases from the atmosphere so that we have a vacuum, and release a stone and a sheet of paper from a skyscraper. Both should get to the ground at exactly the same time because the same force of gravity acted on them.

Wow. So this summarizes the concept of free fall. I'm glad to have learnt something new today.

What an interesting way to explain physics. Nice work man @eurogee
