Operators need to see this.

...what will they do with it?

That's a good idea, but it would require knowing the mass of the player to measure it in Newtons.

Wouldn't your gravity experiment allow you to figure out the mas of the player. Since the player falls at a faster rate you would just have to calculate the velocity of the player and figure out the terminal velocity relative to the minecraft worlds gravitational pull. You then just have to reverse the terminal velocity equation to find the mass I believe.

Is this even possible though? How would you find terminal velocity without knowing air resistance? And all things technically would fall (accelerate anyways)at the same rate(without friction) (be it blocks, players, or items. Even though I don't know if they necessarily do.) so saying that the player falls faster wouldn't totally work from how I see it unless you could find air resistance based on these differences?
Not sure... I'm obviously no wyboth lol
Morrison1996:
Wyboth if you don't already know it here is a link to figure out the air resistance. I believe it should still work with minecraft world physics since they are loosely similar.

The second link if to figure the mas of the object using velocity.

Those are both correct, but you would have to know atmospheric density to solve for mass, which we do not know.
Edit: I have posted both of these articles on Minecraft Forum. Here are the links.
