Whenever you use energy that is work, and to create friction work must be applied to rub two things together, and sometimes fast enough to create sparks depending on the two objects you rub together.
What happens as objects rub together and form sparks?
H
Why is kinetic energy changed to thermal energy when you rub your hands together?
Because when you rub your hands together, it causes the molecules on your hand to move in random motion, which is thermal energy.
