A machine is any device that uses energy In physics, energy is a scalar physical quantity that describes the amount of work that can be performed by a force, an attribute of objects and systems that is subject to a conservation law. Different forms of energy include kinetic, potential, thermal, gravitational, sound, light, elastic, and electromagnetic energy. The forms of energy are to perform some activity. In common usage, the meaning is that of a device having parts that perform or assist in performing any type of work Manual labour is physical work done with the hands, especially in an unskilled job such as fruit and vegetable picking, road building, or any other field where the work may be considered physically arduous, and which has as a profitable objective, usually the production of goods. A simple machine A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage to multiply force. A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to is a device that transforms the direction or magnitude of a force In physics, the concept of force is used to describe how a massive body is affected by acceleration or mechanical stress. Force can also be described by intuitive concepts such as a push or pull that can cause an object with mass to change its velocity , i.e., to accelerate, or which can cause a flexible object to deform.

With the Roman conquest, Latin was spread to countries around the Mediterranean, including a large part of Europe. Romance languages, such as Aragonese, Corsican, Catalan, French, Italian, Portuguese, Romanian, and Spanish, are descended from Latin, while many others, word machina.[1]
