What change could you make to the system that would decrease its total energy?
Understand the Problem
The question is asking for a change that would decrease the total energy of a system consisting of a diver and a diving board. The focus is on how altering aspects of the system, such as the diver's mass or the diving board's height, impacts total energy.
Answer
Replace the diver with someone who has less mass.
The final answer is A. Replace the diver with someone who has less mass.
Answer for screen readers
The final answer is A. Replace the diver with someone who has less mass.
More Information
Gravitational potential energy is directly proportional to mass and height. By reducing the mass, the potential energy decreases.
Tips
A common mistake is confusing how potential energy is affected by mass and height. Remember that both mass and height directly affect potential energy.
