Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. More force results in less energy store change
- B. More force results in greater energy store change
- C. Force has no effect on energy store changes
- D. Force only affects potential energy
Answer
More force results in greater energy store change
Explanation
The correct option is "More force results in greater energy store change". More force results in greater energy store change is right because it directly matches Energy stores and systems: Describe energy-store changes when an object is accelerated by a constant force.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.
Common mistake
Confusing work done with energy stored
Students often think that the energy stored in an object increases simply because work is done on it, without considering the type of energy store and the system’s constraints.
Explain that work done by a constant force changes the energy store of the object (e.g., kinetic, potential, or elastic) only if the force acts over a displacement; the amount of energy transferred equals the work (force × distance) and is stored as a specific form of energy, not as a generic ‘energy increase’.
