What is the unit of mass?

• A. Newton
• B. kg
• C. Pascal
• D. Joule

Answer: (B)

The unit of mass is the kilogram, often abbreviated as kg. This is the standard unit of mass in the International System of Units (SI). When measuring mass, it is essential to use a unit that corresponds to the amount of matter in an object, and the kilogram serves this purpose effectively. Mass is a fundamental concept in physics and is distinct from weight, which is a force that results from the gravitational pull on an object's mass. While the newton, which is the unit of force, can be used to express weight, it is not a measurement of mass itself. Similarly, the pascal is a unit of pressure, and the joule is a unit of energy, neither of which relate directly to the measurement of mass. Therefore, the kilogram is the definitive unit used for mass in scientific contexts and everyday applications.
