A log is floating in place in a pond. A large stone is dropped in the pond which creates waves. The waves move across the pond eventually reaching the log.

What happens to the energy of the log?
What happens to its position? (1 point)
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.
The energy of the log will remain the same. The position of the log will remain the same left to right as well as up and down.
The energy of the log will increase.
The position of the log will remain the same left to right, but it will move up and down.

The energy of the log will increase.
The position of the log will remain the same left to right as well as up and down.

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."
