❔ How to transfer mechanical energy into thermal energy system?

Work is the amount of energy transferred into or out of a system, not counting energy transferred by heat conduction. The conduction of heat is to be distinguished from heating by friction. When a hot potato heats up your hands by conduction, the energy transfer occurs without any force, but when friction heats your car's brake shoes, there is a force involved.

❔ Which device converts rotational energy into electric energy system?

A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades, specifically to mill grain (gristmills), but the term is also extended to windpumps, wind turbines and other applications.
