I introduce g as the strength of a gravitational field due to
the Earth, remind them that it varies with distance, etc, and has
surface.If you wrote that g has a value of 9.8 N/kg at the Earth's
surface, I would agree. But is it correct to add the additional
significant figure and make it 9.81 here??
NY State syllabus (and reference table) now gives it as 9.81, not
9.8 as in previous years. We are obliged to conform.
