### Weight or Mass?

Made a small page on Weight or Mass?

Did I make any blunders?

Nope, can't see any mistakes. I'm pretty sure that page is fully correct. This will be a great help to people, as a lot of them get mixed up and confused between the two key words.

### Re: Weight or Mass?

Agreed. Very nicely done page. One minor quibble - weight is technically measured in Newtons and not kg. But then again, putting the measurements of weight in kg makes the explanation much easier to follow. Maybe there should be a small note somewhere on the page though.

Edit: And goodness me that lift was going very fast.

Why did the vector cross the road?
It wanted to be normal.

Nice page, MathsIsFun!
Weight is referred as kilograms force.
The unit of weight is, therefore, Newton or kgms-² .
Since Force(Newtons) is mass x acceleration, Kg force is used for expressing weight.

Yes, I think a note about Newtons is needed.

But I will put it at the end so as not to confuse (scales that measure Newtons are rare!)
