Re: Quantity, Magnitude, UnitF is the norm or Euclidean distance from the origin of the vector F, There are other types of norms. What is A unit? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20130817 05:55:24
Re: Quantity, Magnitude, UnitThe magnitude is 10 meters. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Quantity, Magnitude, UnitMagnitude is always a positive. A scalar is any number. It can be positive or negative. In mathematics, you don't understand things. You just get used to them.
