Uncertainty value in equation
For the uncertainty value, you add up the total uncertainty right? So for example, if you have 105 m +/- 3 m, the uncertainty value is 6 m? Or is it 3?

In discussion section last week, my TA said to add them up so yes it would be 6!

Yes because the "range of uncertainty" if you would call it that, or margin of uncertainty, is +/- 3 so it's basically the absolute value of 3 times 2.

Re: Uncertainty value in equation
Do uncertainty values always have to be whole integers? also when giving the "total uncertainty" do you always know to just add the numbers or will it ever specify for the range?

Re: Uncertainty value in equation
I also asked my TA and she said it would be 6. There was some confusion because the answer key was wrong for one of the homework questions but it should be double the +- value.

Re: Uncertainty value in equation
Uncertainty values do not always have to be integers. We could have 5 +- 1.3. The uncertainty value would be 1.3(2)= 2.6.

Re: Uncertainty value in equation
yes you add the total uncertainty since it makes it account for both the positive or negative

Re: Uncertainty value in equation
Uncertainty accounts for both the positive and negative, so if your v was 103 +or- 3 then the uncertainty would be 3(2)= 6.
