Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. 50 J
- B. 100 J
- C. 200 J
- D. 500 J
Answer
500 J
Explanation
The correct option is "500 J". 500 J is right because it directly matches Energy stores and systems: Calculate changes in energy when a system is changed by work done by forces.. 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
Common Mistake in Energy Calculation
Students often confuse the work done by forces with the energy stored in a system, leading to incorrect calculations.
Ensure to clearly differentiate between work done and energy changes in a system. Remember that work done by forces results in energy transfer, which can change the energy stores in the system.
