Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. Kinetic energy increases and gravitational potential energy decreases
- B. Gravitational potential energy increases and kinetic energy decreases
- C. Both kinetic and gravitational potential energy decrease
- D. Both kinetic and gravitational potential energy increase
Answer
Gravitational potential energy increases and kinetic energy decreases
Explanation
As an object is projected upwards, it slows down, causing its kinetic energy to decrease while its gravitational potential energy increases due to its height.
Common mistake
Misunderstanding Energy Redistribution
Students often confuse the concept of energy redistribution with energy conservation, thinking that energy is lost rather than redistributed in a system.
Emphasize that energy is always conserved in a closed system; it may change forms or be redistributed, but the total energy remains constant.
