Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. The total energy remains constant
- B. The kinetic energy is fully converted to potential energy
- C. Some kinetic energy is transformed into thermal energy
- D. The object gains additional kinetic energy
Answer
Some kinetic energy is transformed into thermal energy
Explanation
The correct option is "Some kinetic energy is transformed into thermal energy". Some kinetic energy is transformed into thermal energy is right because it directly matches Energy stores and systems: Describe energy-store changes when a moving object hits an obstacle.. 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
Misunderstanding Energy Transfer
Students often think that the energy of a moving object is completely transferred to the obstacle upon impact, without considering energy losses such as sound or heat.
Students should remember that not all energy is transferred; some energy is converted to other forms, like sound or thermal energy, during the collision.
