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).
