A common example of conversion of chemical energy to mechanical energy is in a car engine where the combustion of fuel releases energy that is then converted into mechanical energy to move the vehicle.
Motors convert electrical energy to mechanical energy. Generators transfer mechanical energy to electrical energy.
An electric motor does this
Heat
Sound energy is mechanical energy. No devices are required to make a conversion.
Mechanical energy refers to the sum of potential and kinetic energy in a system, while energy conversion is the process of changing one form of energy into another form. Mechanical energy can be converted into other forms like thermal or electrical energy through energy conversion processes.
It converts mechanical energy into electric energy. .
Mechanical energy can be converted into other forms of energy such as thermal, electrical, or sound energy, depending on the system in which the conversion takes place. This conversion occurs due to the work done by the mechanical energy on the objects or materials involved in the process.
The answer is heat engine.
Chemical (gas) to thermal (combustion) to mechanical More Simply: Chemical Energy to Mechanical Energy
Conversion of electrical energy into mechanical energy
Energy conversion I would say means converting say thermal energy to mechanical, or mechanical to electrical, or other conversions you can think of. Now some machines do this, like electrical generators, or electric motors which is the same but in reverse. Other machines are just mechanical, like a gearbox for example, mechanical energy in and mechanical energy out. So the word machine is more general, energy conversion devices are a sub-set of machines.
