Minecraft Science: Minecart Kinematics

It could be interesting to see the force at which a snowball is thrown (If possible, may require a server, with 1 person throwing, 1 recording).

Just an idea

How about doing one on the pushing force of pistons.

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

That would actually be possible to do with only 1 person. You could use frame analysis and v_f = v_o + at. When the snowball gets to its highest point (possible to determine through frame analysis), v_f = 0, t = the frame number at that point minus the frame number at release times 30, and a = 14.4622. Do some algebra and you've got it.

Thanks!

WOW.

Operators need to see this.

...what will they do with it?

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.

Nope, I understand it too.

[Morrison1996]

I understand it.

[proush600563]

I roughly understand it

[RuthlessTomato]

Let's ALL say we understand it!!!
Just kidding, but you dont all need to
