motor
A motor transfers electrical energy into mechanical energy.
The device which convert mechanical energy in to electrical energy is "Dynamo".
If you mean energy it turns electrical energy into kinetic energy
Electrical generator: A device for converting mechanical (kinetic) energy into electrical energy.
A refrigerator.
An internal combustion engine is a device that converts chemical energy, typically from fossil fuels like gasoline or diesel, into mechanical energy. This energy is used to power vehicles, machinery, and other mechanical systems.
motor
if you mean in terms of energy then it refers to a device that transfers more useful energy than it wastes if you mean in terms of energy then it refers to a device that transfers more useful energy than it wastes
A flywheel is a device that stores mechanical energy by spinning continuously and maintaining rotational motion even after the input energy has stopped.
An electronic motor transfers electrical energy to kinetic energy (movement energy). These use electromagnets, powered by your power source (eg. Batteries).
The motor changes electrical energy into mechanical (torque) energy.
In a microphone, energy transfers from sound waves in the environment to the diaphragm of the microphone. The diaphragm converts these sound waves into mechanical vibrations, which are then transformed into electrical signals by a transducer within the microphone. Finally, these electrical signals are transmitted to an amplifier or recording device for processing or storage.
