A machine is a device that converts one type of energy

A machine is a device that converts one type of energy into another. For example, an engine converts kinetic energy into heat and motion. Engines are used in all sorts of machines, from cars to rockets. Other examples of machines include power plants, which convert chemical or nuclear fuel into electricity; refrigerators, which use electricity or gas to create cooling; mixers, which mix ingredients such as flour and eggs together; and sewing machines, which stitch fabric together using long needles with hooks on the ends.


A machine is a device that uses mechanical power to apply forces, transform energy, or perform physical work. Machines are typically powered by electric motors, but may also be driven by steam, water pressure, wind power or gas. Machines can be classified in many ways: by their function (e.g., a car), by their shape (e.g., a sphere) or by what they do (e.g., mix).


Machines are a type of device that is powered by electricity or other sources of power. A machine can be anything from a computer to a dishwasher or even an excavator. Machines work as they are designed to do, with specific functions such as making food, heating up water for bathing, or lifting heavy objects.


There are many types of machines depending on what their primary function is: some examples are computers, dishwashers, mixers, and bulldozers.
