â Katie, Facebook comment. Hand Rubbing is the act of rubbing the palms of your hands together. The friction of the gesture can be used to provide heat in a cold environment, or it can simply convey excitation or expectation.
The heat from rubbing your hands together is due to the energy being tranferred from mechanical energy (energy in movement) to heat (which is another type of energy in its own right). Another example is when you rub sandpaper on wood.
