A machine is a tool containing one or more parts that uses energy to perform an intended action.

In physics, energy is a property of objects which can be transferred to other objects or converted into different forms.

A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process.


Machines are usually powered by mechanical, chemical, thermal, or electrical means, and are often motorized.

In physics, a force is said to do work if, when acting there is a displacement of the point of application in the direction of the force.

A thermal column is a column of rising air in the lower altitudes of Earth's atmosphere, a form of atmospheric updraft.

An engine or motor is a machine designed to convert one form of energy into mechanical energy.


Historically, a power tool also required moving parts to classify as a machine.

A power tool is a tool that is actuated by an additional power source and mechanism other than the solely manual labour used with hand tools.


However, the advent of electronics has led to the development of power tools without moving parts that are considered machines.

Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role.


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.

In mathematics, magnitude is the size of a mathematical object, a property by which the object can be compared as larger or smaller than other objects of the same kind.

In physics, a force is any interaction that, when unopposed, will change the motion of an object.


Examples include vehicles, electronic systems, molecular machines, computers, television, and radio.

Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width.

A molecular machine, or nanomachine, is any discrete number of molecular components that produce quasi-mechanical movements in response to specific stimuli.

Television or TV is a telecommunication medium used for transmitting moving images in monochrome, or in color, and in two or three dimensions and sound.
