When the waves generated by the stone ripple across the pond and reach the log, the log will experience the energy of the waves.
- The energy of the log will remain the same (assuming there is no external force acting on it that would change its energy overall).
- The position of the log will remain the same left to right, but it will move up and down in response to the waves.
Therefore, the correct option is: "The energy of the log will remain the same. The position of the log will remain the same left to right, but it will move up and down."
