Re: New thing I hate? Questing on Cross Realm

yes, just like your electric bill, youre actually buying joules per month.

However in the context of gas mileage gallons are used as a measure of energy.

So it'd be better to say miles per joule.

Well, kind of, in that a gallon of gasoline has a certain potential energy, and we're trying to measure how much useful output we got from that energy by distance traveled.

But once you start down that route, you can just start applying arbitrary units and eventually we're into furlongs/liter squared or some such nonsense.

You going to answer my Pluto quiz before I go or should I just spill the beans as to what the weight would be on earth?

Well actually you'd have to say a gallon has X joules of energy but the car is only going to operate at Y efficiency so, but a gallon of 93oct has a greater energy density than 86oct.

Well I'm about to leave for the gym so I'm going to give away the answer.

if the object weights 2200N on Pluto it'll weight 37,210N on earth, and has a mass of 3793kg.

Answer this question (it'll take some research)

If have an object that weighs 2200N on Pluto and I bring it to Earth what's it weight on Earth?

about 31.5kN

if you use
»wiki.answers.com/Q/What_is_the_g ··· of_Pluto

.58m/s^2 for g(Pluto) and 9.81 for g(Earth)
then w=mg
so

2200/.58*9.81=37,210.34N
as the significant digits are only at most 2 decimal places its safe to drop the trail off there.

well i guess it was about 7% that of earths or after getting the actual math from unexplainable things web site ill cite it later its 1/15 or .07 which number you choose to use is up to you, anyway pluto is 1/455 the size of earth and 1/5.5 the mass so 5.5 x 5.5/ 455= .07

I would like to see a UI toggle to join group. And it will find the nearest by people with the closest quest progression, and toss them into a group with each other. Then say every 20 or 30 mins it will warn people then it will remake the groups to better fit quest progession and location. If someone drops group, then instant refill. And have a very easy vote to kick. Being kicked from these groups is no big deal, if someone afk's because of what ever, they get vote to kicked and everyone goes on about their business.

Just a thought.

Mass is the amount of matter in an object; mass can be neither created nor destroyed, but can only change form. Weight is dependent on gravity (weight = mass*g, where g = acceleration due to gravity); a paperweight will always have the same mass, but its weight will vary depending on location (Earth vs moon vs Mars vs deep space, etc). Mass is measured in kilograms; weight is measured (usually) in pounds. The density of an object should also be independent of gravity, since density = mass/volume, not weight/volume. (This assumes the object's volume is constant.)

Any other science/measurement/unit questions, feel free to forward them my way.

So to move an object that weighs a tonne would you use and african swallow or a european swallow?

You're not. The references were to a movie Monty Python's The Holy Grail.

If you're going to go that route they might as well set it up the way Rift was. You could join a public group by clicking on somebody and clicking on join group. You could get credit for a kill by joining the group of somebody that was currently killing the mob and then just leaving the group afterwards.

Wrong LBS is weight not Mass

a given object wouldn't change in mass if moved from Earth to Mars but the g (acceleration due to gravity) would be different, even not knowing the exact g of Mars one would know its lower than the g of Earth.

So with W=mg if the mass of the object is the same but the g is lower then the weight will be lower.

So to achev 2200lbs on Mars would require a larger mass than it would on Earth.

And as lbs is a measure of WEIGHT not MASS.

No. Pounds are mass. Pound-force is weight.

kg are like lb
N are like lbf

Another reason I hate our stupid system.

Another reason I hate our stupid system.

To be fair, the term "pound" is used in a very confusing fashion, sometimes as a unit of mass, and sometimes as a unit of force/weight.
»en.wikipedia.org/wiki/Pound_(mas ··· d_(mass)
»en.wikipedia.org/wiki/Pound_(for ··· _(force)

The usual unit of mass associated with the English system (at least that I am familiar with), is the slug:
»en.wikipedia.org/wiki/Slug_(unit ··· g_(unit)

As a scientist (biochemist) living in America, I would be ecstatic if all countries went full metric. I am much more familiar with metric volume measurements, for instance. Metric distances aren't a big problem for me either. (Weather reports given in C instead of F would take some getting used to, though.) Plus, no more having to remember "8 ounces per cup, 2 cups per pint, 2 pints per quart, 4 quarts per gallon" garbage. Just move the fricking decimal place and you're done. Don't even get me started on tablespoons versus teaspoons. However, I doubt that the US will ever switch to metric. Too many people with not enough brainpower to convert the "2 cups of flour" in their biscuit recipe to a metric unit. Multiplication is HARD.

Same thing with ounces versus fluid ounces. I've had to correct a few people when they've pulled out a measuring cup to get 12 ounces of chocolate chips, for example.

Granted, it is used in a confusing way, but I was more concerned with the assertion that pounds are weight and only weight.

I converted myself back in my high school years ('05 was my last year) and haven't looked back. I drive a Civic with an all digital dash. It stays in metric.

I'd be okay with getting 480 mL of flour out.
