Mechanics is the branch of physics which looks at bodies that are influenced by forces and moved.

The discipline has its roots in ancient Greece where Aristotle studied the way bodies behaved when they were thrown through the air (e.g. a stone). However it was Galileo, Kepler and especially Newton who laid the foundations for much of the so called Newtonian mechanics we know today.

A person working in the discipline is known as a mechanician.

Significance[change | edit source]

Mechanics is the original discipline of physics, dealing with the macroscopic world that humans perceive. It is therefore a huge body of knowledge about the natural world. Mechanics encompasses the movement of all matter in the universe under the four forces: gravity, the strong and weak interactions, and the electromagnetic interaction.

Mechanics also constitutes a central part of technology.

Some aspects of classical mechanics[change | edit source]

Newton[change | edit source]

There are three laws of newton. The first is that an object will stay at an constant speed unless a force acts on it. The second is that F= Ma. Finally, the third is that for every action there is an equal but opposite reaction.
