Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change. It is one of the fundamental principles in classical physics , and described by Isaac Newton in his first law of motion (also known as The Principle of Inertia). [ 1 ]
The moments of inertia of a mass have units of dimension ML 2 ([mass] × [length] 2). It should not be confused with the second moment of area, which has units of dimension L 4 ([length] 4) and is used in beam calculations. The mass moment of inertia is often also known as the rotational inertia, and sometimes as the angular mass.
The moment of inertia is defined as the product of mass of section and the square of the distance between the reference axis and the centroid of the section. Spinning figure skaters can reduce their moment of inertia by pulling in their arms, allowing them to spin faster due to conservation of angular momentum.
Often when editing on Wikipedia disputes will arise between editors; be it a fact stated in article, a change to a Wikipedia policy, or even the colors on a template. When two parties arguing a side feel strongly enough about their stance, there is a strong probability that a lack of development can occur.

The Grigore Antipa National Museum of Natural History (Romanian: Muzeul Național de Istorie Naturală „Grigore Antipa”) is a natural history museum, located in Bucharest, Romania. It was originally established as the National Museum of Natural History on 3 November 1834. [ 1 ]
Introductory section of the Childhood Memories second chapter, in its manuscript form. The second section opens with another nostalgic soliloquy, which famously begins with the words: "I wouldn't know what other people are like, but for myself, when I start thinking about my birthplace, Humulești, about the post holding the flue of the stove, round which mother used to tie a piece of string ...
