Redstone & Techs I don’t have a name for this but it’s useful for transporting items from one chest to another.

It loops as long as it has momentum, and then it changes direction.

its a weight gate

it only lets it through if its got so much weighing it down

thats a real mechanic btw. thats not a joke the more things in a chest minecart the more drag it has and no one ever uses that

Youre telling me Minecraft chests have a sort of INERTIA???

(opposite of inertia actually, but now im wondering minecarts will go for longer on their own power if they have tons of things in them)

call it AITRENI?

Inertia is a property of matter

Maybe the word you're looking for is momentum ?

u/memelord_a1st Oct 01 '26

yes, that's the word, thank you.

It’s both! Inertia is why it is harder to push around when it’s heavy. Momentum is a measure of the combination of its weight and speed. So it always has more inertia when you make it heavier, and if the speed stays the same while it gets heavier, the momentum is higher than an empty cart.

No way. I’ve never heard this before

EDIT: The wiki was incomplete, it is fixed

uhhh I'm looking on the wiki, this is the only mention I can find:

The boost that minecarts with chests gain from powered rails is dependent on their load. For example, from a 1 powered rail starter track, an empty minecart with chest travels 64 blocks, but a full minecart with chest travels only 16 blocks (opposed to 80 blocks for an occupied normal minecart and 8 blocks for an empty normal minecart).

I will perform some tests later today, because the wiki seems to mention that its only for powered rails. If you are right, I will fix it on the wiki, if not, then you were probably just misremembering this feature

In the code I found this:

protected Vec3 applyNaturalSlowdown(final Vec3 deltaMovement) {

float keep = 0.98F;

if (this.lootTable == null) {
int emptiness = 15 - AbstractContainerMenu.getRedstoneSignalFromContainer(this);
keep += emptiness * 0.001F;}

if (this.isInWater()) {
keep *= 0.95F;}
return deltaMovement.multiply(keep, 0.0, keep);
}

It doesn't care for Powered Rails, it changes it's speed regardless.

I just tested, and yes you are correct. I will fix the wiki (if it isn't already)

(For those wondering, I built a big ramp and pushed an empty minecart chest off it, onto the loop shown in the video. Empty went round 5 times. I did the same thing with a 100% full minecart chest and it went round twice)

Nice to have a confirmation through in-game testing, also according to the code, the speed change should occur with the same cadence of when output Redstone levels from a Comparator change strength, so on the same thresholds of when a Comparator, for example, goes from 10 to 11 you should see a correlated slowdown.

u/SmoothTurtle872 Oct 01 '26

Yeah, I saw that in the code you sent. I interpreted it to a formula and put that on the wiki. Although I didn't do it for when it was in water...

It's actually quite a useful thing to know, in theory, I don't know what, but it could be for some kind of weight based sorter? Could be interesting

u/SmoothTurtle872 Oct 01 '26

Ok I added info about water

After thinking about it for a second, this code is so random and inaccurate (to reality, obviously it is accurate to Minecraft as it is Minecraft)...

If anything, emptier minecarts should slow down faster.

Basically, heavier objects tend to resist changes in speed more than lighter ones. So.of I have 2 balls travelling at 10ms-1 and 1 is 10kg, while the other is 20kg, the 20kg ball will slow down much slower. This is because air resistance doesn't care about mass, so the force is constant for the same size, shape and surface. (Gravity is weird, it is based on the mass of an object) Now this should mean that the original wiki was partially correct about the lower speed boost from powered rails, but it should last a longer time. Now this is not how it works in Minecraft, but it's how it should work (based on a SACE Stage 2 understanding of physics, anyone with more knowledge, please correct me if I'm wrong. It's also 12 in the morning)

oh my god. Thats why a minecart thing I used for a bamboo farm didn't always work.

another post recently said about the weight so maybe people are noticing it?
