Question
- A. Kinetic energy to gravitational potential energy
- B. Kinetic energy to thermal energy
- C. Thermal energy to kinetic energy
- D. Gravitational potential energy to kinetic energy
Answer
Kinetic energy to thermal energy
Explanation
The correct option is "Kinetic energy to thermal energy". Kinetic energy to 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.
