Science Questions

So I got this question and I have no idea wtf its talking about.. not much into science please help someone!

A wooden baseball bat and an aluminum bat have the exact same shape, size and mass. Aluminum is much denser then wood. Explain how the two bats could be the same size and mass?

Grundie · 09-09-2007, 08:11 PM

The aluminium bat is hollow?

Sarod · 09-09-2007, 08:16 PM

Pretty much what grundle said.. since aluminum is denser than wood it requires less volume (thats why they're hollow) to achieve the same weight as wood. Unless i r just being retarded

They are the same mass, but weigh different amounts.

Don't mix up mass and weight!

so one's on a different planet?

Weight is determined by mass and gravity, and the question said nothing about weight.

ok so whats the answer to the riddle?

Bladefury · 09-09-2007, 08:26 PM

They are able to have the same mass because they have different weights.

Because the aluminum is denser, it weighs more, but the mass is still the same.

thanks guys, foh forums never fails

what is the measurement of mass? Though mass and weight aren't the same, I thought they were linearly correlated?

If both bats are the same mass, just say 1 kilogram, and are the same size and shape, why do they have a different weight in Newtons?

I guess what I am asking is that if 2 objects that are the same shape and displace the same volume, and are also the same mass (1000 grams), they should weigh the exact same.

A pair of 1000 gram baseball bats should weight the same, when measured in Newtons...?

Kilivek2.0 · 09-09-2007, 08:40 PM

weight is with gravity in effect

mass stays the same anywhere

weight and weight in newtons changed with whatever force gravity is acting on it.

atleast i think so, hell i just failed to solve a 3rd grade riddle.

Objects with the same mass have the same weight assuming they are experiencing equal gravity. Bladefury doesn't know what hes talking about, density has nothing to do with it.

It would if you remembered them correctly.

As long as the force from gravity acting on them is the same then yes objects of equal mass will weigh the same.

edit: ^Damn you.
