Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. Kinetic energy decreases while gravitational potential energy increases
- B. Gravitational potential energy decreases while kinetic energy increases
- C. Both kinetic and gravitational potential energy decrease
- D. Both kinetic and gravitational potential energy increase
Answer
Kinetic energy decreases while gravitational potential energy increases
Explanation
The correct option is "Kinetic energy decreases while gravitational potential energy increases". Kinetic energy decreases while gravitational potential energy increases is right because it directly matches Energy changes in systems: Identify apparatus and techniques used in specific heat capacity practical work.. 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 Apparatus
Students often confuse the purpose of different apparatus used in specific heat capacity experiments, such as calorimeters and thermometers.
Review the function of each piece of equipment and how it contributes to measuring temperature changes and energy transfer in the experiment.
