A machine is a tool containing one or more parts that uses energy to perform an intended action. Machines are usually powered by chemical, thermal, or electrical means, and are often motorized. Historically, a power tool also required moving parts to classify as a machine. However, the advent of electronics has led to the development of power tools without moving parts that are considered machines.
A simple machine is a device that simply transforms the direction or magnitude of a force, but a large number of more complex machines exist. Examples include vehicles, electronic systems, molecular machines, computers, television, and radio.
The word derives from the Latin word machina, which in turn derives from the Greek (Doric μαχανά makhana, Ionic μηχανή mekhane "contrivance, machine, engine", a derivation from μῆχος mekhos "means, expedient, remedy"). The word mechanical comes from the same Greek roots. However, the Ancient Greeks probably have borrowed the word "mekhane" from the ancient Hebrews. The word "Mekhonot" plural and "Mekhona" singular mentioned in the Hebrew Bible - Torah; these "Mekhonot" were the ten contraption on four wheels that stood at the Holy Temple of Jerusalem, built by King Solomon-(2 Chronicles 4:14). The ancient Greeks were familiar with the Hebrew Scriptures and language, and often borrowed words and terms.
A wider meaning of "fabric, structure" is found in classical Latin, but not in Greek usage.
