    Is there any specific device to convert mechanical energy to heat energy?

    What are some devices that come to mind for you? How much energy are we talking about?

    Is this for homework, BTW? If so, I can move the thread to the Homework Help forums.

    if someone slaps somebody on the cheek with his hand, the hand will be stopped (= loose its mechanical energy) and the cheek will warm up a little (= gain heat energy)

    try it yourself one day (you might have to repeat it a few times to raise the cheeks temperrature by a measurable amount, so make sure the person you slap knows that it is done in the name of science).
