Brain Teasers
Heavy Blocks
There are three blocks on a table: a 1 kilogram block, a 500 gram block, and a 2 kilogram block.
What is the weight of the heaviest block on the table?
What is the weight of the heaviest block on the table?
Hint
Make sure you understand what the question is asking you.Answer
About 19.6 Newtons.Weight is a force caused by gravity, and so is measured in Newtons. Mass, how much "stuff" in each block, is measured in kilograms.
By Newton's Second Law: Force = Mass * Acceleration. The acceleration due to gravity on the Earth's surface is about 9.8 Newtons/Kilogram, so Force = 2 * 9.8 = 19.6 Newtons.

ok? im not into science much...
It doesnt say that they are made of the same matrial. This way, the small one could way more than the biggest one if it is made of a heavier material.
I don't think it's a trick teaser... i think this is miscategorized and should be a science teaser.
The material shouldn't matter. A kilogram of feathers has exactly the same mass and weight as a kilogram of lead, doesn't it?
jsdodgers, if 1 kilogram of feather is the same weight is 1 kilogram of metal. They are all 1 kilogram!
Jsdodgers has a point: this teaser states that the MASS is a kilogram. Mass is different from weight; it's just how much space an object takes up.
Anyway, this would make an excellent science teaser, and it will probably be moved, so I will treat it as such.
I didn't get the answer, but I learned something new. Nice job!

And congrats on your first teaser, Emmanovi! (Sorry for the double post, but I had to say it.)
Wow, my brain didn't go there at all! Time for bed. Good teaser though.
belongs in science.
i'm not a science freak! but we did learn about mass and newtons and stuff in school! that one was hard maybe you sould make it easy!
Just because it is science based, doesn't make it a science teaser. It is a trick.
Nice teaser.
Nice teaser.
Nice teaser... I got 20 newtons because I learned to round it to 10. But I know it's 9.8 Great job!
Quite clever, but I didn't get it even though I learned this concept (or something similar, anyway) in high school chemistry class a few weeks ago.
I got to the point where I realized it was newtons or pounds. I just didn't feel like doing the math.
Okay learning about Newtons right now yet still didn't know that
I thought that there was no way to tell because the masses were given instead of weights.
still belongs in science, good though, i guess
this one was lame...
definitely a science trivia question.
otherwise a good one
otherwise a good one
i think you should have put that in science category
easy squeezy lemon peezey, really should have been in science teasers though
????
More Science than trick...
When I read the word Newtons, I was like oh maaaan. I understand his point and I agree, this is better off with Science.
although its kinda nit picking, you should mention that you are on earth, if your in space then all of them would technically weigh nothing.
Forgot the equation to newtons, but realised what it was asking. This is definantly sciencey.

you never said on which planet the experiment was conducted
How much do you weigh? answer in newtons - I think not sir
What does a butcher weigh?
What does a butcher weigh?
That shouldn't be in the trick category. It isn't obvious and requires previous knowledge.
i didnt come here for a science lesson :l
What...? Consider me well teased! I'm bad at math & science.
This was soooo easy. Man,I need a difficult science teaser now.
