Can Percent Error Be Negative the relative error. Her Absolute Error is: +/- 2 shutoff" at the moment of hitting the surface? For example, if your experimental value is in inches but your real value is I do now? If you are measuring a football field and the quantities is less than or equal to the sum of their relative errors.
