Question

What happens when you square an uncertainty?

Answer 1

Answer:

If you are raising an uncertain number to a power n, (squaring it, or taking the square root, for example), then the fractional uncertainty in the resulting number has a fractional uncertainty n times the fractional uncertainty in the original number. Thus if you are calculating a number y = ½ g t2 , where t = 2.36 ± .

Answer 2

Explanation:

If you are raising an uncertain number to a power n, (squaring it, or taking the square root, for example), then the fractional uncertainty in the resulting number has a fractional uncertainty n times the fractional uncertainty in the original number. Thus if you are calculating a number y = ½ g t2 , where t = 2.36 ±
