Question

A group of students use a scale to measure the mass of an object. Which of the following would be the appropriate base unit of measurement to use: a meter b Liter c gram d Newton e none of these

Answer 1

Answer:

c Gram

Explanation:

Mass is an intrinsec property of every object; it is somehow a measure of the "amount of matter" contained in the object.

The SI units of the mass is the kilogram (kg), where one of the sub-multiple of the kilogram is the gram (g). For measuring small objects, therefore, the gram is the appropriate unit.

The other units are wrong because:

- The meter is the unit of measure of the length

- The liter is a unit of measure for the volume

- Newton is the unit of measure for the force
