Because it is a common misconception that mass and weight are the same thing. In fact, they are different physical concepts that measure different aspects of an object.
Mass is the amount of matter in an object, while weight is the force of gravity on that object. Mass is denoted by m or M and is constant in every location. Weight is denoted by W and varies by location.
For example, if you have a mass of 70 kg on Earth, you will have the same mass of 70 kg on the Moon. However, your weight will be different, because the Moon has less gravity than Earth. On Earth, your weight will be about 686 N (newtons), while on the Moon, your weight will be about 113 N1.
Therefore, the term “mass” does not refer to the same physical concept as weight. The correct answer to your question is False.
