How can you explain why weight is expressed in Newton and mass in Kg
Answers
Answer: This may help you
Explanation:
Far more of the English speaking part of the world deals with commerce, trade, law, and other similar professions than with physicists and engineers. Contrary to the world of physics and engineers (and contrary to the proclamations by physics and engineering instructors and textbooks), the world of commerce, trade, and law uses the word “weight” as a synonym for, and instead of, the word “mass”. This has been true for over 1000 years—far longer than the just over 300 years that physicists have tried to redefine the word “weight” to mean a particular type of force and invent needlessly a new word “mass” to mean amount of inertial material.
Because they are using the word weight to mean mass, the only appropriate SI unit for weight in such a context is the unit of mass, the kilogram (and similar units related through prefixes as gram, milligram, etc.).
Answer:
- Weight is actually Force by which earths gravity attracts a person on its surface
- Mass is the tendency of body to resist acceleration when force is applied
- Mass of a body is constant at a particular moment
- But weight can change when we go to other planets
