Considering the law of conservation of energy, we believe that a super-duper bouncy ball should keep bouncing - forever. Yet, we know that it eventually stops.
How is energy conserved or is it?

When a super-duper bouncy ball bounces, some of its energy is converted into sound energy, which is released into the surroundings as sound waves. Additionally, due to the ball's internal friction and the interaction with the surface it bounces on, some of its energy is converted into thermal energy, which escapes into the surroundings as heat. Therefore, energy is conserved but transformed into different forms.
