You can classify scales for weighing objects as those that use springs and those that use standard masses to balance unknown masses. Which group would be more accurate when used in an accelerating spaceship? When used on the moon?
Solution 8DQ Step 1 of 2: In case of locally uniform gravitational field or uniform acceleration, we can use a beam balance to measure mass without actually having the know value of the magnitude of the acceleration due to gravity. In order to use the spring balance, first we need to calibrate the instrument first,as on the earth, the gravity varies . Once it is calibrated ,it is easy to use in a stable gravitational field like on the surface of planet or large moon.
