    Interesting! On the Minecraft wiki (at minecraft.fandom.com/wiki/Transportation#Vertical_transportation ) you can find posted the actual formula for the downward velocity of a falling player. I don't know much about applied math, but I would imagine the gravitational acceleration to be the derivative of the velocity at time 0. Calculating that gives the actual value of Minecraft's "little g" as -1568*ln(50/49), or about 31.678 blocks/sec² downward. Not too far off from the value you found!
    Do note that Minecraft doesn't have uniform gravity; different entities fall at different speeds (and I'm not just talking about chickens 😛)

    Measuring time with warped fungi and hoppers are creative but that's 0.2 seconds of uncertainty which is huge in this context.
    You could've fallen onto the tripwire hook right when the hopper cooldown of 0.4 seconds have ended and caused the last warped fungus to not get into the chest.

    This has messed with me for a few days. But I figured out why. Minecraft earth has denser gravity then our earth. So minecraft steve would be able to jump around on earth like he was floating? Also that means he could run faster on earth?(given he got use to the gravity). It bothers me because there are videos about how much weight minecraft steve can hold. But 1x1x1 meter of gold here is lightwe then 1^3 meter of gold there.
    Also minecraft steve can run 5-6 blocksper second. That might be the reason behind minecraft mechanics not to allow the character to by pass that speed with out potions. That would be interesting if drinking a speed potion would allow you to fall faster.
    But I have a conversions question.
    If 1^3 meter to 100^3 centimeters is 1,000,000. Is 0.71^3 meters to 100^3 centimeters equals 357,911correct?
    Because google and all online sources say 0.71 cubic meters is 710,000. Which is 100x100x71. In centimeters. Since 1^3centimeters is 1x1x1.
    Same for 1^3 foot to 12^3 inches is 1,728. And 0.5^3 feet to 12^3 inches equals 216. But if I do 0.5 feet times 12^3 I get 864.
    Since cubic is the word for ^3. And that provides the formula
    ( A^3) x (B^3) =(C^3)

      @@DrWeselcouch there is alot in the conversions that don't make sense. If you google. .71cubic meters to liters. It says 710.
      Buy 71 cubic centimeters is .071.
      But if it's really 0.71^3 meters and 71^3 centi meters. Both answers are 357.911 liters.
      And I just checked the weight of 1^3 centimeters. 19.28grams. Vs 1^3 meter is 19.282kilograms. And that adds up to 1 million 1^3 centimeters so that adds up fine. Which I find weird.
      Because (A^3) × (B^3) = (C^3) is no where on oeis.org or a google search. Only the formula
      A^3 + B^3 +C^3 =0 are brought up.
      Nor does the formula
      (A^x) x (B^x) = (C^x)
      Which I have been randomly checking and seems to hold. And I only figured it out because of that weird 0.71 conclusion I got to and found that the greeks did too.
      But i feel like (A^2) + (B^2) =(C^2)
      Might be at fault. Since (A^3) + (B^3) = (C^3) doesn't work in higher powers. It's weird how there are so many hits and misses.
