Responses

As the potential energy increases, kinetic energy decreases. Total energy increases.
As the potential energy increases, kinetic energy decreases. Total energy increases.

As the potential energy increases, kinetic energy increases. Total energy stays the same.
As the potential energy increases, kinetic energy increases. Total energy stays the same.

As the potential energy increases, kinetic energy increases. Total energy increases.
As the potential energy increases, kinetic energy increases. Total energy increases.

As the potential energy increases, kinetic energy decreases. Total energy stays the same.

The correct answer is: As the potential energy increases, kinetic energy decreases. Total energy stays the same.
