The Physics of Minecraft: Gravity

NOTE: Big apology to all those who can't watch Physics due to some GEMA conflicts. We're working out a half-solution right now.

What is the gravitational acceleration in Minecraft?
Let us find out!

-------------------------

About the initial height:

TLDR: It's negligible

I only noticed the initial height after I recorded the video, but I conducted additional experiments on the significance of this.
The initial height only affects the the maximum height, which causes the maximum height to be 42 instead of 43. Both the time and the horizontal distance are the same.

If the initial height is taken into account, the gravitational acceleration would be 17ms^-2. All the values used and measured were rounded to two significant figures, which mean that the last digit falls within the expected variation in error with significant figures.

The error from the height is negligible compared to the error in measurement.

This is a just parody of science videos. If we really wanted to find how minecraft physics worked, we would just look at the code.

@MrLukasLindwasser Well, I doubt the change of day to night really affects the physics. If you wanted to make time a bit more relevant to Minecraft, you could use ticks, which are a tenth of a second. Minecraft updates every tick.

Can you re-upload it without the music? German users can't see the video due to a copyright claim by GEMA. Thanks.

[nopefully]

@icebraining I (y2bd) will ask Silent_Boom about that. I'm quite perplexed about that withstanding issue, I thought that we had dealt with it. I'll be sure to tell you once we sort it out!

[MrLukasLindwasser]

but how did you convert the distance in minecraft into meters? if you just assumed a block was a meter i dont think this data is correct

[nopefully]

@MrLukasLindwasser I believe Notch asserts that one block = one meter.

(o-o) its quite simple really

[lokphakwod]

minecraft is SERIOUS BUSINESS

skip...skip...skip...skip...

PLEASE MORE

[beechcraft12]

o.o go on...

I CANT BRAIN TODAY I BRAIN MY SPRAIN!

Oops... Didn't think of initial height -_-' it's quite the same though.

[Jio1557]

I can't do physics but I'm quite good with Maths. I estimated the function f that gives the vertical position depending of the horizotal position ( i don't know how you call abscisse and ordonée in English >< ). This function is approximatively y=-0.018x^2+1,773x (exactly -172/9409x^2 + 172/97x). I did some trigonometry with f(0)=0 and f(0,05)=0,08861. I found an inital angle of atan(0,08861/0,5), which means approx 10 degrees.

I mean : yeah, i know what gravity is. That was just a question because I don't know how I can persnally check it.
