Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. Energy is conserved and remains unchanged
- B. Energy is transferred to the obstacle
- C. Energy is converted into thermal energy
- D. Energy is transformed into kinetic energy
Answer
Energy is converted into thermal energy
Explanation
When a moving object hits an obstacle, some of its kinetic energy is converted into thermal energy due to friction and deformation.
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.
