The U.S. National Institute of Standards and Technology (NIST)maintains several accurate copies of the international standard kilogram.Even after careful cleaning, these national standard kilograms aregaining mass at an average rate of about 1 mg/y (y = year) when comparedevery 10 years or so to the standard international kilogram. Doesthis apparent increase have any importance? Explain.

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.
