Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. Kinetic energy decreases and gravitational potential energy increases
- B. Kinetic energy increases and gravitational potential energy decreases
- C. Both kinetic and gravitational potential energy decrease
- D. Both kinetic and gravitational potential energy increase
Answer
Kinetic energy decreases and gravitational potential energy increases
Explanation
The correct option is "Kinetic energy decreases and gravitational potential energy increases". Kinetic energy decreases and gravitational potential energy increases 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.
