What is rubbing your hands together is what type of energy?

Rubbing your hands together generates mechanical energy. This is because when you rub your hands together, the friction between them causes the molecules in your skin to move and generate heat energy. Rubbing your hands together quickly and more vigorously can increase the amount of mechanical energy generated, resulting in more heat being produced. This is why rubbing your hands together is often done to warm them up on a cold day.
