Question
- A. In the free-body diagram scenario, apply elastic potential energy to explain why doubling extension more than doubles elastic potential energy while keeping elastic versus plastic deformation separate.
- B. In the free-body diagram scenario, mix up elastic versus plastic deformation and ignore elastic potential energy.
- C. Use a general revision statement without applying Elastic potential energy to the situation.
- D. Choose a different forces topic instead of explaining explain why doubling extension more than doubles elastic potential energy.
Answer
The correct answer is: In the free-body diagram scenario, apply elastic potential energy to explain why doubling extension more than doubles elastic potential energy while keeping elastic versus plastic deformation separate.
Explanation
The correct option is In the free-body diagram scenario, apply elastic potential energy to explain why doubling extension more than doubles elastic potential energy while keeping elastic versus plastic deformation separate.. It is correct because the scenario says arrows show the size and direction of forces on one object, which must be interpreted through Elastic potential energy. This directly supports the learning objective to explain why doubling extension more than doubles elastic potential energy. Use values 8, 5, and 11 only if the question asks for a calculation. The answer earns credit by naming the relevant force or motion quantity, using units when needed, and avoiding the boundary error elastic versus plastic deformation.
Common mistake
Misunderstanding Elastic Potential Energy
Students often think that doubling the extension of a spring will double the elastic potential energy stored in it.
Students should understand that elastic potential energy is proportional to the square of the extension, so doubling the extension actually increases the energy by a factor of four.
