Why does it make more sense to provide relative errors, such as: δν δm δρ 2 V m P instead of absolute errors: SV, 8m, Sp? Before you answer, think of a measurement of your height with an error of 10 cm and a measurement of the distance from New York to Los Angeles with the same error. What can you say about the absolute and relative errors for these measurements? Which one is more accurate?

Why does it make more sense to provide relative errors, such as:
instead of absolute errors: SV, Sm, Sp? Before you answer, think of a
measurement of your height with an error of 10 cm and a measurement of the
distance from New York to Los Angeles with the same error. What can you say
about the absolute and relative errors for these measurements? Which one is more
accurate?
