Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. Energy is conserved as it transforms from kinetic to gravitational potential energy
- B. Energy is lost to the environment as it transforms from gravitational potential to kinetic energy
- C. Energy is created as the object rises
- D. Energy is destroyed when the object reaches its peak height
Answer
Energy is conserved as it transforms from kinetic to gravitational potential energy
Explanation
The correct option is "Energy is conserved as it transforms from kinetic to gravitational potential energy". Energy is conserved as it transforms from kinetic to gravitational potential energy is right because it directly matches Energy stores and systems: Describe energy-store changes when an object is projected upwards.. 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 Changes
Students often think that the energy store remains constant when an object is projected upwards.
Emphasize that as an object is projected upwards, kinetic energy is converted to gravitational potential energy, leading to a change in energy stores.
